Need for long-term observations

Climate and land use change are key factors influencing the terrestrial hydrological system which need to be managed by society in the coming decades. Therefore optimal management and sustainable use of water resources require the availability and valorization of long-term monitoring data related to the water status of the terrestrial system from the local to the catchment scale as well as validated and integrated hydrological models. Long-term observations are needed in order to detect complex interaction and feedback mechanism between the various compartments of the hydrological system and to identify long-term trends in observed states and fluxes.


Research focus

The combination of comprehensive multi-scale and multi-temporal measurements of terrestrial system states and fluxes with physically based simulations is a prerequisite to improve our understanding of hydrological processes and to validate integrated terrestrial models. The process-oriented and hypothesis-driven observation of landscapes and catchments requires the development of new and the improvement of existing surface- and subsurface characterization and environmental sensing concepts and technologies. Their application should allow a comprehensive and quantitative description of reference catchments with respect to the complex variety of environmental parameters and fluxes.
