Evapotranspiration (ET) from soil and vegetation is a key part of the energy and water budgets and, with condensation, a process that links both explicitly. Accurate experimental determination of ET is a requirement yet challenging both in situ and remotely. It introduces uncertainties for model parameterization development and validation. Furthermore, …

How forests can increase hydrological drought
Forests are known to have a negative effect on water yield (the total annual streamflow). However, little is known about the effect of forest on hydrological droughts. Considering the relatively high evapotranspiration of forest, hydrological droughts might be expected to increase when forest establishes. The effect of forest on hydrological …

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 …

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 …
