The impact of drought on vegetation does not increases proportionally with decreasing soil moisture content. The so-called critical soil moisture content below which evapotranspiration reduction and vegetation impact rapidly increase is a key parameter, but knowledge on the critical soil moisture is limited due to a lack of soil moisture …

New model for computationally efficient modeling of floods and droughts
Many distributed hydrological models are computationally demanding, limiting their use in calibration, sensitivity analysis, or scenario analysis. Based on the theory that many catchments behave essentially as simple dynamical systems, Joost Buitink recently developed a distributed model that does not have this limitation and can be run on a normal …

PhD students are expected to follow several courses as part of their training plan. One of these courses is the A2, which is aimed at increasing the impact of, and communication about the PhD research. To fulfil the requirements of the course, Marta Antonelli produced a nice video explaining hydrologic …

Lower soil moisture conditions are known to positively contribute to warmer temperatures, in particular during heatwaves. Inner East Asia is one of the regions where this coupling is likely significant. Writing in Science, Zhang and co-workers found that the recent coincidence of drought and hot temperatures is unprecedented in a …
