HydroTalks: Dr. Hossein Hashemi on Groundwater Monitoring and Water Management in Arid Regions

Podcast promotional graphic titled HYDRO TALKS EPS. 12, featuring a central silver microphone and three people in yellow circular frames against a blue background with a yellow soundwave.

For this month’s episode of HydroTalks, we’re thrilled to welcome Dr. Hossein Hashemi, an associate professor in the Division of Water Resources Engineering at Lund University in Sweden and a member of the Center for Advanced Middle Eastern Studies. His research focuses on groundwater and surface water management in arid and water-scarce regions, combining remote …[Read More]

How can we check if a simulated heatwave is plausible?

A white thermometer with a red liquid column stands in tan sand. The background shows a bright sun in a blue sky with light clouds.

Extreme heatwaves of unprecedented magnitude are expected to become increasingly frequent in coming decades. These heatwaves come with severe consequences for human health, infrastructure planning, and economic prospects – particularly during events lasting multiple weeks [10]. In recent decades, Western Europe has become a hot-spot for record-breaking and long-lasting heatwaves [9], raising a critical question: …[Read More]

In the News: Flood wave in Nepal: climate disaster or not?

A snow-covered mountain peak rises into a deep blue sky, partially obscured by thick, white clouds. The steep, jagged slopes are bright white with visible vertical ridges.

By Aris Kwadijk, PhD candidate, Mountain Hydrology group, Department of Physical Geography at Utrecht University, and Walter W. Immerzeel, Professor, Mountain Hydrology group, Department of Physical Geography at Utrecht University. Email: a.kwadijk@uu.nl, w.w.immerzeel@uu.nl. Website: https://www.uu.nl/medewerkers/AKwadijk, https://www.uu.nl/medewerkers/WWImmerzeel. Was the catastrophic flood wave in the Himalaya on 26 August a consequence of climate change, and therefore the fault of the …[Read More]

The spice must flow: The Geodynamics of Dune

A person stands in silhouette atop a golden sand dune, holding two objects. They are surrounded by vast, undulating dunes under a pale sky.

Everyone wants something from Arrakis. The Emperor wants control, the great houses want spice, and the Fremen would quite reasonably like everyone else to leave. I would settle for a geological map. Preferably with a few cross-sections, although I realise that asking someone to carry a seismic survey across sandworm territory might complicate the risk …[Read More]

Fieldwork and Family: Parenting in the Biogeosciences

Four people stand side by side in colourful rain boots, their footwear heavily coated in dark brown mud. They are standing on a thick layer of wet, dark brown soil.

It took almost two years to write this blog post – not because the challenges described below are rare, but because the scarcest resource for parents in academia is uninterrupted time. Academic careers are built on time: time to think, to meet collaborators, to develop the next research proposal, and to finally get that paper …[Read More]

The dam upstream: why flood warnings fail the White Volta Basin and what we can do about it

Map of Ghana and Burkina Faso showing the White Volta Basin in light blue, a green validation domain, and the locations of a dam and a gauge. An inset map shows the region's location in West Africa.

On 25 August 2025, SONABEL – Burkina Faso’s national utility – began releasing water from the Bagre Dam two days ahead of schedule. The reservoir had reached 90% of its capacity, just 0.73 metres below its maximum retention limit [9]. The Water Resources Commission and the National Disaster Management Organization (NADMO) in Ghana issued immediate …[Read More]

Which rain and temperature should drive your model? A guide to select daily forcing datasets , with application to northern Italy

Which rain and temperature should drive your model? A guide to select daily forcing datasets , with application to northern Italy

If you want to run a hydrological model  anywhere, the first question is which meteorological forcing to use. For the Po basin, or anywhere in northern Italy,  there are today at least a dozen gridded products, regional and European, built from different meteorological networks, with different methods and for different purposes. I reviewed them from …[Read More]
