Protecting springs from groundwater extraction: is a ‘drawdown trigger’ a sensible strategy?

Protecting springs from groundwater extraction: is a ‘drawdown trigger’ a sensible strategy?

By Matthew Currell – Senior Lecturer at RMIT University Springs, some of which have been flowing for hundreds of thousands of years, have been disappearing in Australia due to human water use over the past century. Following a hotly contested court case, Australia’s Environment Minister imposed a 20cm ‘drawdown limit’ at a set of springs, to protect them from a proposed coal mine. However, this ig ...[Read More]

Human Drought?

Human Drought?

By Anne Van Loon – a water science lecturer at the University of Birmingham Recently I published a commentary in Nature Geoscience with the title ‘Drought in the Anthropocene’. In that commentary, my co-authors and I argued that in the current human-dominated world, we cannot study and manage natural drought processes separately from human influences on the water system like water abstraction, dam ...[Read More]

One hell of a great groundwater textbook now available free

One hell of a great groundwater textbook now available free

‘Groundwater’ the seminar text book from Freeze and Cheery (1979) is free in pdf now…just follow the links here. This text book is almost as old as I am and important parts of modern hydrogeology are rusty or non-existent (like hydroecology amongst other topics) but it is still lucidly written and useful.  I routinely send students to read chapters so I am happy that it is now available free. Kudo ...[Read More]

The new and exciting face of waterunderground.org

by Tom Gleeson I started waterunderground.org a few years ago as my personal groundwater nerd blog with the odd guest post written by others. Since I love working with others, I thought it would be more fun, and more interesting for readers, to expand the number of voices regularly posting. So here is the new face of the blog… What is the new blog all about? Written by a global collective of ...[Read More]

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 ...[Read More]

Cruisin’ for Deep Sea Vents

My friend John Jamieson, who is now a prof in the geology department at Memorial University in Newfoundland and Canada Research Chair in marine geology and is also a former GeoSphere guest poster is currently on a research cruise near Fiji. John researches deep sea vents, aka. black smokers/seafloor massive sulphide deposits that are exhaling super heated water at tectonic plate boundaries around ...[Read More]
