Bedrock: A hydrogeologist’s devotional

Bedrock: A hydrogeologist’s devotional

Post by Kevin Befus, Assistant Professor at the College of Engineering and Applied Science at the University of Wyoming, in the United States.

_______________________________________________

I want to share a book with you that has encouraged me through initial academic mires (I was only in graduate school for 7 years…) and inspired me to expand my perception and appreciation of the natural world.

The book is Bedrock: Writers on the Wonders of Geology [Savoy et al., 2006]. It is a carefully curated collection of snippets and excerpts from international literary sources describing geologic processes and outcomes. Most of the writings come from the 20th century with several exceptions extending not quite as far back as the Pleistocene. Each chapter, or collection of writings, is oriented around a theme in the earth sciences, one of which is “Rivers to the Sea”…the creative views of hydrologic, mainly riverine, processes chapter. While the excerpts are the main event in each chapter, a quick introduction to each selection is given within the broader geologic context along with some reasoning in why each was chosen.

Bedrock is not a book about hydrogeology, and it really doesn’t directly talk about water underground. BUT, Earth is explored in the excerpts, and developing connections between groundwater and other geologic processes is our job, not the literary masters who “contributed” tidbits to the book. As you should have expected, John McPhee shows up a number of times, but not too much. Many of the early geologists (e.g., G.K. Gilbert, James Hutton, and John Wesley Powell) and environmentalists (e.g., Rachel Carson and John Muir) also share their reflections of geologic forces on nature.

As someone who reads blogs about groundwater, remember to extend the literary reflections to include how the topics interact with groundwater systems. For example, the cover image evokes excitement (or consternation) from a groundwater hydrologist, as it shows the coastline of Nullarbor Plain in southern Australia, home to the “world’s largest limestone karst area” (http://www.australiangeographic.com.au/travel/destinations/2016/04/hidden-nullarbor).

My suggestion for reading this book is to take it slow: one excerpt in the morning to kick-start the day, remembering why it is you do what you do. Be inspired, awed, and reminded of how geological processes have shaped our world over billions of years. Or, read an entry when the day has taken a turn to the slow or chaotic. Like any good devotional, Bedrock has great re-readability and also points you towards the original documents for more in-depth explorations of literary (hydro)geology.

Happy reading!

Community advice to young hydrologists, Part 1

Community advice to young hydrologists, Part 1

We at Water Underground loved reading Young Hydrologic Society’s post titled “Community advice to young hydrologists” – an advice column written by a network of established scientists in the field. We appreciated the column so much, in fact, that we have decided to re-blog the post to you (with YHS’s consent, of course). We’ve split up their post by question, and have added in hyperlinks to all contributors and related material (as has always been our inclination). Happy reading!

Question: What book or paper has been most influential to your career and why?

Groundwater by Freeze and Cherry – this textbook, now out of print, was a critical reference as I began my graduate training in hydrogeology and I still refer to it today.

Jean Bahr (University of Wisconsin)

 

 

 

 

 

 

.

I can think of no single one.  However, papers that were a combination of field observations and clever analyses leading to new insights always are intriguing.  Papers which I find of little value are those that propose a new modeling approach with little to no field verification, or which use existing models to reach some conclusion.  For example, we seem to be seeing a proliferation of papers using complex models to highlight some “new” effect of climate change on the hydrologic cycle, with no grounding in hindcasts. (See this, also) The musings of Keith Beven always have been insightful, including his Advice to a Young Hydrologist.

Jerad Bales (CUAHSI)

 

.

I can’t identify single “most influential” books or papers – I learned early to read as widely as possible, and not just within narrow/specific research problems of direct interest. I have been inspired by a range of articles – including books on philosophy, history of physics, etc. – which broadened my approach and ways of looking at a given problem. Indeed, some of my most influential work developed from studying methods and approaches in statistical physics and physical chemistry.

Brian Berkowitz (Weizmann Institute of Science)

 

.

The most important influence was a person – Mike Kirkby and particularly the undergraduate course on quantitative hydrology he taught at the University of Bristol when I was taking my degree there (later, I would do a post-doc with him at Leeds that resulted in the development of Topmodel). That gave me a lot of reading to do – but it was probably not the hydrological reading that had most influence, but rather the papers on theoretical geomorphology starting with Horton BGSA 1945, then picked up by Kirkby, Frank Ahnert and others in the late 1960s. I struggled to understand them (at the time I wanted to be a geomorphologist but I have never quite finished getting the water part right) but they left me the idea that it was possible to theorize about environmental processes and systems in approximate but useful ways.

During my PhD the most influential paper was undoubtedly Freeze and Harlan JH 1968, and the papers about the field site I was applying my model to by Darrell Weyman (HSB 1970, IAHS 1973). If I had talked to him a little more (he was doing his PhD at Bristol while I was an undergraduate) or read those papers more carefully, then I might have been more realistic in my PhD modelling.

The most important book at that time was Zienkowicz, Finite Element Modelling (that was the technique I was trying to master). Hillslope Hydrology edited by Kirkby was also important but came later.

Keith Beven (Lancaster University)

Paper: Scale of Fluctuation of rainfall models by I. Rodriquez-Iturbe. It formed the basis for my MSc research that I did during 11 months in Davis California (As a Dutch Student from Wageningen). It was extremely difficult stuff, but I kept on it and it understanding gave me the stamina to really dig into a subject. It was the basis for my first paper entitled “Analytically derived runoff models based on rainfall point processes” in WRR. To obtain better background I also read in depth the influential.

Book: Random Functions and Hydrology by R. Bras and I. Rodriquez-Iturbe.

.

Konrad and Booth (2005), Hydrologic changes in urban streams and their ecological significance, American Fisheries Society Symposium, 47:157-177.  This paper is a bit outside my area of expertise, but I think the linkage they make between physically measurable streamflow changes and stream ecology represents a fundamental shift in thinking from engineering hydrology to more of an eco-hydrology perspective.  They illustrated that we need to go beyond analyzing just changes in peak flow or low flows (or fixed percentiles), to look at more derived metrics that better capture hydrologic regime change.

Laura Bowling (Purdue University)

That is a very hard question. As a Geography undergraduate student, I had to write a particular essay on the “all models are wrong” theme and this involved critiquing two papers which completely changed my worldview about models and modelling: Konikow and Bredehoeft’s 1992 ‘Ground-water models cannot be validated’ Advances in Water Resources 15(1):75-83.  and Beven’s 1989 ‘Changing ideas in hydrology – the case of physically-based models’ Journal of Hydrology.

But in the last year, I would say it has been Lab Girl by Hope Jahren (2016) who is a gifted and talented scientist and writer and has the knack of intertwining the natural world with tales of remaining brave in your career. I wish I’d had the opportunity to read it earlier in my career.

It is a novel by Milan Kundera: “Slowness”. My natural tendency is to rush up, be as fast as possible, quickly fix things… Yet, speed often leads to miserable outcomes. Many lines of Kundera’s book are still in my mind, and they work as a continuous reminder for me that only slowness allows thoughtful consideration, serious reflection, and appreciation of reality. Realizing this has strongly influenced my academic career as it made me focus on the quality (and not the quantity) of my work.

Giuliano Di Baldassarre (Uppsala University)

 

.

Several hydrogeology-related texts were very helpful for me.  These include some of Mary Hill’s papers, John Doherty’s PEST manual (as much for the philosophy as the instruction), some of Jasper Vrugt’s early papers, and work by both Wolfgang Novak and Steve Gorelick on measurement design. The real recommendation would be to find authors that you enjoy and read as much of their work as possible – in this category, I would add Shlomo Neuman, Randy Hunt, Hoshin Gupta, Dani Or, Keith Beven and Graham Fogg. I am sure that I am forgetting more than I have listed. I think it is equally important to read broadly. Rather than provide a list, I’ll encourage you to look at my recent paper in Ground Water (Sept 2016) for some suggestions!

Book:  Groundwater Hydrology by David Keith Todd, 1st edition, 1959. As a 3rd-year undergraduate in hydrology at the University of New Hampshire in 1973, this book (and course by Francis Hall) kindled my interest in groundwater and completely changed my career path, which previously was essentially an aimless sleepwalk through my major in mathematics.

Paper/report:  Kaiser, W. R., Johnston, J. E., and Bach, W. N.. 1978, Sand-body geometry and the occurrence of lignite in the Eocene of Texas: The University of Texas at Austin, Bureau of Economic Geology Geological Circular 78-4, 19 p.  This paper demonstrated in stunning detail how modern borehole geophysical data together with understanding of the geologic genesis of sedimentary deposits could be used to create unprecedented subsurface maps of aquifer/aquitard system heterogeneity and structure. This led me down the long path of better integrating groundwater hydrology and geologic depositional systems.

Graham Fogg (UC Davis)

My interests have been in predictive hydrometeorology. The following were influential books at the start of my carrier in the late 70s and early 80s: Dynamic Hydrology by Eagleson; by Wallace and Hobbs; Applied Optimal Estimation by Gelb (ed).  These represented the fields of hydrology, meteorology, and estimation theory with applications to prediction, and were the necessary pillars to build predictive hydrometeorology.

The paper that has been most influential to my career is most certainly  “Johnston, P. R., and D. H. Pilgrim (1976), Parameter optimization for  watershed models, Water Resources Research, 12(3), 477–486. I read this paper during my graduate work in the early 1980’s and was intrigued by their report that “A true optimum set of (parameter) values was not found in over 2 years of full-time work concentrated on one watershed, although many apparent optimum sets were readily obtained.”

On the one hand this paper clearly identified an important problem that needed to be addressed. On the other (as I often remark during talks on the subject), I think it was remarkable as an example of a paper reporting the apparent “failure” of the researchers to achieve their goals … how often do we see people reporting their failures in the literature these days :-). More of this kind of work – reporting a scientific study and accurately reporting both successes and failures … but especially failures … is critically important to the progress of science, so that people can both contribute to solutions and also avoid unsuccessful forays down paths already tried.

In any case, the paper clearly pointed me towards an important problem that led to me adopting a path of research over the past decades, which led to the development of the SCE and SCEM  optimization algorithms (and indeed a whole field of optimization developments), studies into impacts of model structural deficiencies, multi-criteria methods for parameter estimation, the diagnostic model identification approach, and more recently the Information Theoretic approach.

The 1990 paper by Michael Celia et al on the numerical solution of Richards equation, recommended to me by Philip Binning at the beginning of my Honours Project at Newcastle Uni. This paper made a big impression on me because it provided a very clear exposition of how to solve a challenging modelling problem – and played a bigly role in getting me interested in research.

Dmitri Kavetski (University of Adelaide)

The Ecological Studies Series, published by Springer, was the most influential in my career because several books published in the Series (e.g., Forest Hydrology and Ecology at Coweeta edited by Swank and Crossley and Analysis of Biogeochemical Cycling Processes in Walker Branch Watershed edited by Johnson and Van Hook) sparked my interest in forest hydrology and biogeochemistry. In tandem with the superb mentorship of Prof. Stanley Herwitz (Clark University), I decided to embark upon a career as a forest hydrologist as a sophomore in college. I never looked back.

Delphis Levia (University of Delaware)

 

 

 

.

The papers of the series “Plants in water-controlled ecosystems” (2001, Advances in Water Resources 24), by Laio, Porporato, Ridolfi, and Rodriguez-Iturbe have been among the first and most influential I have read. Their clean, analytical approach to the complex interactions among vegetation, soil, and climate remains deeply inspiring. As an example of inter-disciplinary work (actually outside hydrology), I would like to mention the book by Sterner and Elser (2002) “Ecological stoichiometry. The biology of elements from molecules to the biosphere” (Princeton University Press) – a great example of how integrating knowledge from various sources around a common theme can yield deeper understanding and perhaps even lay the foundation of a new discipline.

Stefano Manzoni (Stockholm University)

 

.

The Hewlett and Hibbert 1967 conference paper “Factors affecting the response of small watersheds to precipitation…” is perhaps the best paper ever written in hydrology. For a full homage, please look here. The paper is field-based, theory focused and a blend of bottom-up and top-down research, before that was even ‘a thing’. It inspired me in my graduate research in the 1980s; I continued to read it and ponder it in my first years as a professor, as I strived to follow in Hewlett’s footsteps. He was my mentor even though he retired before I could ever meet him.

Jeff McDonnell (U Saskatchewan)

 In general, the books that have been most influential to me refer to sister disciplines. The reason is that I found illuminating to study methods and models used in statistics and economics for the purpose of applying them to hydrology for the first time. Thus, the most influential book to me has been “Statistics for long-memory processes”, by Jan Beran. The very reason is that I found there a detailed explanation of models that were useful to get to target with my Ph.D. thesis.

Chamberlin TC. 1890. The method of multiple working hypotheses. Science 15: 92-96 (reprinted in Science 148: 754–759 [1965]). I read this paper as part of a second-year course in Archaeology, which I took as an elective in my undergraduate program. Although the writing style is somewhat archaic, this article introduced me to the value of hypothesis-based thinking in science and the need to avoid favouring a pet hypothesis or model. It is instructive also to read the many follow-up essays to gain a broader perspective on hypothesis-based research and, more broadly, the “scientific method.”

Dan Moore (University of British Columbia)

I think I was more influenced by my peers, colleagues, mentors, supervisors and friends as I learn better through discussions and challenges. One of the more memorable papers is one of Manning (Manning, R. (1891). “On the flow of water in open channels and pipes,” Transactions ofthe Institution of Civil engineers of Ireland.) and it’s associated history. In this paper he actually suggested a far more ‘complex’ formulation than the formula which is today widely known as the Manning equation – history has it that it was never adopted widely as well as many subsequent more more sophisticated formulations. Science doesn’t work linear and we are sometimes less rational or objective (if the latter is actually possible) than we believe.

Florian Pappenberger (ECMWF)

“Show me a person who has read a thousand books and I’ll show you my best friend; show me a person who has read but one and I will show you my worst enemy.” I have been influenced by many and I can’t say one is *the* most influential or important alone.  At the moment, I am reflecting on (McCuen RH. 1989. Hydrologic Analysis and Design. Prentice Hall: Englewood Cliffs.) As far as being a hydrology textbook it is not particular special, but it is written extremely clearly with a lot of good step-by-step workflows.  Most importantly, the book integrates throughout its whole development the concept of analysis versus synthesis, and this has been central to how I approach my research.  We do both analysis and synthesis.

Gregory Pasternack (UC Davis)

.

This is very difficult to say. I must admit that my academic work started from engineering practice and I only started reading the international literature very late in my career. But a book that has been very influential to me was the book by Fischer et al. (1979) “Mixing in inland and coastal waters”. Fischer soon died in an accident after this book was published. The book introduced me to the fundamentals of mixing processes in estuaries, on which I had done substantial field research and had developed my own practical engineering method, which I still use, but which lacked a fundamental theoretical basis. I am still working on finding this fundamental basis, and Fischer’s book put me on that track.

It would be tough to answer what’s been the most influential to my career as a whole, but I could answer what was the most influential to my early career, and that was Menke’s Geophysical Data Analysis: Discrete Inverse Theory.  I labored through that book for years during my PhD. My copy has dog-eared pages and writing throughout as I tried to figure out inversion methods.  Finally getting my head around the mathematics of inversion really opened up some doors for me early on.  Davis’ Tools For Teaching also really helped me think about how to be as effective a teacher as I could be.

It is difficult to select one single work from the literature that has been influential over my entire career in groundwater flow and transport modeling.  But, there is one book that I used as a grad student that I still refer to today.  It is “Conduction of Heat in Solids” by Carslaw and Jaeger.  The book is a treatise on analytical solutions to diffusion equations.  The lesson for me is that knowledge from other disciplines (in this case thermal engineering) can be applied to problems in hydrology.  Another lesson is that we can learn a lot and gain important insights through wise approximations that have analytical solutions.

In hydrology, some of the most influential books for me have been Handbook of Hydrology (edited by David Maidment) and Principles of Environmental Physics (Monteith & Unsworth). These two books are so rich in physics, empirical equations, recipes, and references. Of course the times have changed and nowadays you can google almost anything, but some of the chapters in these books are so well written that I still regularly use them. They also have the benefit that they summarise areas of research where things haven’t actually changed too much since the 80ies – the physics we use haven’t become that much more sophisticated, and sometimes in fact less so; whereas the field measurements on which a lot of the empirical rules and equations are based generally also haven’t been added much to since.

Outside hydrology, some books that have made me think differently about the field and my research include

Emergence: The Connected Lives of Ants, Brains, Cities, and Software (Johnson) – one of the first popular science books I read that made me think different (about ecohydrology)

The Sceptical Environmentalist (Lomborg) – I didn’t accept his reasoning but it was seductive and it forces you to really pick apart the logical and rhetorical flaws he uses.

Thinking, fast and slow (Kahneman) – which really made me realise the questionable quality of my analytical rigour and decisions in general (also those of anyone else, though!).

Comparative hydrology, edited by Malin Falkenmark and Tom Chapman (1989). This book is one of the first to examine global hydrology phenomena. It asserts that a comprehensive and systematic description of hydrological processes is (i) possible (ii) not too complicated. Until then I’d thought the task was impossible, so I found the approach inspirational for my research.

Everything is connected

Everything is connected

__________________________________________________

In recent years the human dimension of hydrology has become increasingly important. Major flood and drought events have shown how strongly water and society are intertwined (see here and here). The hydro(geo)logical research community is increasingly including this human dimension, for example within the IAHS Panta Rhei decade (link), which focuses on the interface between environment and society and aims to “make predictions of water resources dynamics to support sustainable societal development”. Previous Water Underground blog posts have shown the importance of this topic and highlighted opportunities and methodologies for scientists to engage with socio-hydro(geo)logy and humanitarian projects. Viviana Re, for example, introduces the term socio-hydrogeology and promotes sustainable groundwater management in alliance with groundwater users (link). And Margaret Shanafield argues that humanitarian groundwater projects are “an opportunity for scientists to have an impact on the world by contributing to the collective understanding of water resources and hydrologic systems” (link).

In our interdisciplinary project CreativeDrought (link), which uses local knowledge and natural and social science methods to increase local preparedness for uncertain future drought, we are applying these ideas and we realise how important different types of connections are in our two-way learning process. We just completed our second fieldwork phase of the project that consisted of workshops in which groups of people from a rural community in South Africa experimented with potential future drought scenarios and created stories about how they would be impacted by the drought and what they could do to prepare for and adapt to it. Our scientific team consisted of hydrologists and social scientists from local and UK-based institutes and the groups in the community who participated were the village leaders, livestock farmers, irrigation farmers, young mothers, and elderly people.

Both the scientific team and the community groups were interested to learn from each other’s knowledge and experience (or just curious, see photo below of our Zimbabwean colleague Eugine measuring irrigation canal discharge with an apple). During the time we spent in the community (four weeks in March/April and two weeks in July) we both learned about important connections. As hydrologists and hydrogeologists we know that different parts of the hydrological system are connected and that these connections are extremely important if you want to understand, predict, and manage the system. Knowledge about the connection between groundwater and surface water is what we as hydrologists could bring to the community. The community was getting their water from different sources: drinking water from a groundwater well, irrigation water from a reservoir that releases water into the river, and water for bathing, washing, brick making, and cleaning cars from the river. By showing how a drought would affect each of these water supplies and discussing amongst groups that would be affected differently by a drought, they learned about the connection between the water bodies and how abstraction in one would affect the other.

Researchers measuring discharge with help of schoolchildren and collecting stories about previous droughts and floods (photos: Anne Van Loon and Sally Rangecroft).

We scientists also learned some important connections from the community. For example, our project focuses on drought but when we asked the community to tell us about droughts they had experienced in the past, many also told us about flood events. For the community, both are water-related extreme events that often even impact them similarly, with crop loss, drinking water problems, diseases, etc. Even though floods and droughts are governed by different processes (floods by fast, mostly near-surface pathways and droughts by slower, sub-surface storage related pathways) and different tools and indices are used to characterise both extremes, people at local scale have to deal with both floods and droughts when the hydrological system goes from one into the other or when both occur simultaneously in different parts of the hydrological system. We realised that our academic world is so fragmented that we often forget about connecting floods and droughts in our scientific work. Furthermore, we forget that we may affect one hydrological extreme when trying to manage our resources for the opposite hydrological extreme.

The most important, but unintended connections we discovered, however, were the connections between people. During our stays in South Africa, we connected as hydrologists and social scientists and between the UK-based and local researchers, learning to communicate across different disciplines, languages and audiences. The project also helped the community rediscover some connections between generations (young mothers and elderly ladies) and between different sectors (livestock farmers and irrigation farmers). And finally, we as a scientific team connected with the community. As a token for our newly established connection, the children’s dance group performed traditional dances during our final visit with the chief and the village leaders (see below), only bestowed on very special guests. That is the best confirmation we could get that personal connections are important and that our water management and our science depend on them!

Everyone connected: researchers, village leaders, dancers (photo: Khathutshelo Muthala).

Crowdfunding Science: A personal journey toward a public campaign

Crowdfunding Science: A personal journey toward a public campaign

Post by Jared van Rooyen, MSc candidate in Earth Science at Stellenbosch University, in South Africa.

Part one of three in a Crowdfunding Science series by Jared.

___________________________________________________________

When my supervisor, Dr Jodie Miller, suggested to me last year that we should look at crowdfunding as a way to potentially to fund my master’s project, I had no idea of what I was about to get myself into. All through my honours year I was not really interested in doing further postgraduate study. She kept warning me that I might change my mind and that I should apply for funding “just in case”. But I was sure of my position.  And then, as I started the final five weeks of my honours year, I finally got to focus 100% on my research project. Suddenly, as I focused in on my data, all the possibilities started to leap out at me. I went from a BSc (Hons) student, who was not considering continuing my postgraduate studies at all, to someone who is passionate about water resource research and continuing my postgraduate career. This is apparently common amongst postgraduate students in science, who become exponentially more immersed in their field of study as they realise that their work isn’t just numbers and experiments, but has significant real world applications.

Once I had committed – there was no turning back. The learning curve for mounting a successful crowdfunding campaign is steep and slippery. As much as it is hard, stressful work it is also fulfilling, fun, and full of surprises. The biggest obstacle is one that most modern day scientists are confronted with already: How do I make my research attractive to people who don’t have years of passion invested in my work?

Well, the answer is not simple.

I have completed a wide variety of modules in my tertiary studies but none in any forms of multi-media marketing skills. So naturally, when I had this crowdfunding campaign in front of me, I was so far out of my comfort zone that I felt like a geologist at a slam poetry evening. After numerous conversations with my peers who had experiences in marketing and graphic design, I had gathered a basic understanding of the inner workings of the unfathomably enormous media machine.

From the very first day I arrived back at the University in Stellenbosch I was drowning in ideas and administration. Setting up the social media accounts alone was a mission. Little did I know that running a social media campaign takes days and even weeks of preparation and planning each public post, including the post’s time, target market, outcome goals, and context. Each post on each platform had to be vetted and boosted appropriately. I was genuinely missing the late nights combing through complicated scientific articles and pounding through textbooks.

Making the campaign video was by far the hardest but definitely the most fun part of the process. The hours and hours of footage I have of retakes and drone videos culminated in, what I believe, is the pinnacle of my creative career (which is minuscule).

About a week before the initial launch date, we ran into some red tape within the University. Naturally, as someone who has never done anything more than post a couple photos of rocks on Instagram, I had no idea that a project like this needed to go through a number of stages before being approved by the university (which included: legal, ethics, corporate, marketing, and the faculty itself). A couple of panic-ridden meetings and documents later, we were ready for lift off, although a week later than originally planned.

As a geologist, I am not afraid of hard work, so engulfing myself in learning as much as I could in the little time I had came more naturally. What was most intimidating though, was the thought of putting myself and what I am passionate about out there. Publicly declaring the fact that what I wanted to achieve was not funded was daunting at first, but in time became a revelation in self-awareness and that asking for help is more constructive than admitting defeat.

I believe that postgraduate crowdfunding may prove to be invaluable in the future of students that have all the potential but their projects remain unfunded. Not only does it allow for the financial security of your project, but it attracts people that are interested in your field to you and to your work. The most significant consequence of this crowdfunding approach is that when you graduate, you already have a network of people in the industry that know who you are and know of your potential.

The crowdfunding campaign was completed in early April of 2017. In the next blog I will talk about what worked and what didn’t work, who pledged funding and how did we reach them.

What led me down the slippery slope into a career in hydrology and then hydrogeology, was a desire to combine my love of traveling with a desire to have a deeper relationship with the places I was going, and be able to contribute something positive while there. I figured everyone needs water, and almost everyone has either too much (flooding) or too little of it.

But, from an academic point of view, aid/humanitarian/philanthropic projects can be frustrating and offer few of the traditional paybacks that universities and academia reward.  Last week, for example, I spent much of my time working on the annual report for an unpaid project, and I am soft money funded. And what’s worse, I couldn’t even get the report finished, because most of the project partners hadn’t given me their updates on time. When I went across the hall to complain to my colleague, he admitted that he, too, was in a similar situation.

So what is the incentive?

Globally, the need for regional hydrologic humanitarian efforts is obvious. Even today, 1,000 children die due to diarrhoeal diseases on a daily basis. Water scarcity affects 40% of global population, with 1.7 billion people dependent on groundwater basins where the water extraction is higher than the recharge.  And, the lack of water availability is only going to get worse into the future.

But being a researcher with pressure to “publish or perish” and find ways to fund myself and my research, what was/is my incentive to address these problems? From an academic point of view, water aid projects are often time-consuming, with expected timelines delayed by language and cultural barriers, difficulties in obtaining background data, expectations on each side of the project not matching up, and activities and communication not happening on the timescales academics are used to. And the results are typically hard to publish.

An online search revealed numerous articles discussing the pros and cons of pursuing a career in development work, including: having a job aligned with one’s morals and values, an exciting lifestyle full of change, motivated co-workers, the opportunity to see the world and different cultures, the opportunity to make a difference, and last but not least, because it is a challenge (in a good way).

As a scientist, I get elements of all these pros in my daily work. But, while much of what academics do fits under the umbrella of “intellectually challenging”, aid projects provide applied problems with real-world implications that can sometimes be lacking in the heavily research-focused academic realm, except for the creative “broader impacts” and outreach sections of grant proposals. They are therefore an opportunity for scientists to have an impact on the world by contributing to the collective understanding of water resources and hydrologic systems. And hey, many of us enjoy travelling and get to visit interesting places for work, too.

Pulling myself out of my philosophical waxings, I focused on these highlights and the benefits of working in an interdisciplinary project to address some of those global problems I mentioned earlier – and got back to report writing.

Good groundwater management makes for good neighbors

Good groundwater management makes for good neighbors

Dedicated Water Underground readers know that this blog is not just about water science, but also some of the more cultural impacts of groundwater. Keeping in that tradition, today’s post begins with a joke*:

Knock, knock!

Who’s there?

Your neighbor

Your neighbor who?

Your neighbor’s groundwater, here to provide water for your plants!

Figure 1. Typical reaction to joke written by the author.

Ahem.

Perhaps this joke needs a little explanation. As we’ve covered before, groundwater is important not just as a supply of water for humans, rivers, and lakes, but also because it can increase the water available to plants, making ecosystems more drought resistant and productive. However, we also know that groundwater moves from place to place beneath the surface. This means that human actions which affect groundwater in one location, like increasing the amount of paved surface, might have an unexpected impact on ecosystems in nearby areas which depend on that groundwater.

Imagine, for example, two neighboring farmers. Farmer A decides retire and sells his land to a developer to put in a new, concrete-rich shopping center. Farmer B continues farming her land next door. How will the changes next door affect the groundwater beneath Farmer B’s land, and will this help or hurt crop production on her farm?

In a new study, my colleagues and I explored these questions using a series of computer simulations. We converted different percentages of a watershed from corn to concrete to see what would happen. Our results showed that the response of crops to urbanization depended on where the land use change occurred.

Figure 2. Conceptual diagram showing how urbanization might impact crop yield elsewhere in a watershed. From Zipper et al. (2017).

In upland areas where the water table was deep, replacing crops with concrete caused a reduction in groundwater recharge, lowering the water table everywhere in the watershed – not just beneath the places where urbanization occurred. This meant that places where the ecosystems used to be reliant on groundwater could no longer tap into this resources, making them more vulnerable to drought. However, places where the water table used to be too shallow saw boosts in productivity, as the lower water table was closer to the optimum water table depth.

In contrast, urbanization happening in lowland areas had a much more localized effect, with changes to the water table and yield occurring primarily only in the location where land use changed, because the changes in groundwater recharge were accounted for by increased inflows from the stream into the groundwater system.

So, what does this mean for the neighboring farmers we met earlier?

For Farmer A, it means the neighborly thing to do is work with the developers to minimize the effects of the land use change on groundwater recharge. This can include green infrastructure practices such as rain gardens or permeable pavement to try and mimic predevelopment groundwater recharge.

For Farmer B, the impacts depend on the groundwater depth beneath her farm. If the groundwater beneath her farm is shallow enough that her crops tap into that water supply, she should expect changes in the productivity of her crops, especially during dry periods, and plan accordingly.

Just in case you weren’t sure…groundwater flow around a fault zone is complex!

Just in case you weren’t sure…groundwater flow around a fault zone is complex!

By Erin Mundy – a plain language summary of part of her Masters thesis

Groundwater is the water that collects underground in pores and cracks in the rock. Understanding, protecting and sustaining groundwater flow is critical because over two billion people drink groundwater every day. The flow of groundwater can be impacted by geologic structures, such as fractures and faults. A fracture is a break in the rock; a fault is a break in the rock where the rocks move relative to each other (ie. one rock will move up, one rock will move down, as seen in Figure 1).

CTF1

Figure 1. Diagram of a thrust fault

Faults can act as barriers slowing down groundwater flow, they can be a conduit speeding up groundwater flow, or amazingly they can act both slow it down and speed it up!

How groundwater moves through these rock structures is difficult to directly observe because it all happens underground and rarely exposed on the surface. The Champlain thrust fault at Lone Rock Point in Burlington, Vermont, provides a unique opportunity to study groundwater flow around a fault because approximately 1 km of the fault is exposed along the edge of Lake Champlain (Figure 2). Here, an older rock

(yellow) is thrust over a younger rock (black). No one has studied groundwater flow around this fault in detail, so we hoped to find out a basic understanding of the relationship between the fault and groundwater flow at this location.

To understand groundwater flow around this fault, we did three things: 1) we walked along the fault and made note of changes in the fault (ie. the width of the fault, the angle of the fault, the shape of the fault, etc.); (2) we looked for areas where groundwater was leaking from the rock surface (this is known as groundwater seepage – we wanted to see if there was a relationship between where groundwater was leaking out and the changes in the angle/width of the fault); and (3) we drilled three wells and then pumped water out of these wells. We pumped water out of one well and measured the water level in the other wells – this gives you an idea of how the groundwater moves. For example, if you pump water out of one well and the water level in a nearby well declines drastically, this suggests that the water is easily moving through the rock. So if you’re pumping water from the fault and that happens, then the fault is most likely channeling water along the fault. If the opposite happens, then the fault may be acting as a barrier to groundwater flow.

We found four main geologic structures at the Champlain thrust fault: (1) the main fault, (2) an area where the fault splayed into many smaller faults, (3) areas where the fault thickness increased to 3 m, and (4) areas where there are traces of older, cemented fault rock (Fig. 3).

Hanging wall is the older rock; footwall is the younger rock. a) main fault; b) fault splay; c) increased fault thickness; and d) older abandoned fault rock

We found 19 areas along the rock where groundwater was leaking out of the cliff (Note: This was done in the winter so the groundwater was frozen into ice). We found that most of the groundwater seepage occurred in the younger (black) rock, with a few at the fault and where the fault splays out into smaller faults (Figure 4).

CTF4

While drilling the two wells at the site, we had two unexpected problems. One, there was a large difference between the depth of the fault in the two wells. The fault depth in one well was 27.4m, while in the other well (which was 10 m away), the fault depth was 70 m. This suggests that there must be another fault in between these two wells that offsets the fault depth. The other unexpected complication was that we drilled into 1.8 m and 2.1 m caves beneath the ground. Caves are common features in limestone, but the rock at our site is a dolostone, which is usually more resistant, so caves are an interesting find! The pumping test revealed a complex system. Further testing is needed to better refine these results.

Combining the data from the surface and subsurface observations, we created a preliminary three-dimensional model of the Champlain thrust fault (Figure 5). Where the rock is exposed at the edge of Lake Champlain, the fault thickness varies, splaying out into smaller faults and showing traces of older fault rock. Groundwater is leaking out of the younger rock (footwall) and along the fault. At the well-site, the fault is offset by another fault and caves are present. The three approaches we used (geology, seepage, pumping tests) all revealed different aspects of the Champlain Thrust fault, and exposed the complexity of groundwater flow around faults.

A social media dashboard for researchers – taming the digital anarchy for nerds

A social media dashboard for researchers – taming the digital anarchy for nerds

Is anyone else overwhelmed by updating their many webpages, blogs, streams etc?

Jason Priem described the shift from a paper-native academia to a web-native academia, in an excellent article last year in Nature, a shift well beyond the traditional peer-reviewed journal to more diverse outlets of information, interaction and discussion. I am part of the first generation of researchers who are excited to use social media but we need more and better tools to make social media work even better for ourselves and others. Something like HootSuite for Prof 2.0!

I love Hootsuite, a dashboard for managing various social media profiles  (twitter, facebook etc.) in one handy place, across multiple platforms (phone, computer, tablets etc.). It looks something like this…

hootesuiteWe need something similar to manage the various facets of academic life. Just to give you some idea, these are all the pages and sites I try to maintain: personal research webpage, this Water Underground blog, twitter, LinkedIn profile, Google scholar, ResearchGate, ResearcherID, Vimeo, Groundwater footprint. I am happy to do this but it can be overwhelming in the midst of the other pulls of academic life – and I don’t even use facebook!

Ideally, this new platform would be a simple, user-friendly, open-source dashboard that would integrate various social media outlets academics use, plus be a simple place to update citations. A great and relatively simple first step would be a single place to update reference lists, which are a crucial part of how academics are evaluated so it is useful to keep them updated. Currently, my references are listed on Google Scholar, ResearchGate, ResearcherID, as well as a couple university webpages. It would be great to be able to export citations (already in standard formats like EndNote or BibTeX) and have these citations populate and update all my reference lists. I know Google Scholar already does this automatically (and usually correctly) but it would be great for consistency across outlets.

It would be great to link all kinds of altmetrics with this simple, social professor dashboard. Altmetrics are alternative metrics to the widely-used journal impact factor and personal citation indices like the h-index. An aggregate metric is calculated from how much as article, person, event (or blog post – subtle hint!) is viewed, discussed, saved, cited or recommended. As Priem writes, altmetrics will “draw new maps of scholarly contribution, unprecedented in subtlety, texture and detail.” And I find this to be already true – I often follow meandering altmetrics paths from a scientific article to news articles or discussions about the scientific article, and then I use this to enrich blog posts or tweets.

I flit across the web throughout my day and week – this dashboard would help me stay grounded and organized on the web. When I publish a new article, I would automatically update it in the various the places listing my citations, then write a quick tweet about it, check for news articles about it etc. Or I may see a comment on LinkedIn about a scientific article that could be useful for a paper I am writing. The comment in one column of the dashboard would be linked to the article, and the PDF posted on ResearchGate may be in another column of the dashboard. I take the PDF, export the citation to my library and pop it into the paper I am working on, in a series of smooth, integrated steps.

This HootSuite for Prof 2.0 could be a simple tool to enable the shift from a paper-native academia to a web-native academia by leveraging and extending information, interaction and discussion.
