Hydrologic Models in the course of time

Within the water science community a wide range of hydrological models exist that were originally developed for describing specific hydrological processes, fluxes and storages at different time and space scales. In recent years, hydrology has moved far beyond its original scope, both with respect to detail and thematic boundaries. Hydrologic processes are becoming more and more interlinked with the processes taking place within the atmosphere, vegetation and the groundwater compartment. Designing more complex hydrological models or coupling different hydrological models today has become a widespread approach in the hydrological community worldwide.


Research focus

The focus is set to the creation of a large ensemble of structurally different but comparable hydrological models with the aim to quantify the sensitivity and the predictive uncertainty on hydrological models conditioned on high dimensional spatially resolved observation.

In addition, in order to deliver comprehensive uncertainty estimates for the hydrological system to decision makers the uncertainty of future weather and climate projections will be propagated through the ensemble of hydrological models.
