Investigation of hillslope-riparian-stream-groundwater interactions:
Monitoring, Modelling and Sensitivity analysis

This study, conducted in collaboration with the Forschungszentrum Jülich, is about the application of the complex integrated coupled model ParFlow-CLM.

Since this model is very computationally expensive, it has to run on high-performance computers (such as the Lichtenberg II of the TU Darmstadt) and extensive calibrations with a high number of parameters are hardly possible. To reduce the number of parameters and thus the computational costs of a calibration, our goal is to analyze particularly relevant parameters in a sensitivity analysis. Simulations are carried out for three different catchments: Wüstbach, Rollesbroich and Stettbach. While the first two are intensive monitoring sites of the TERENO network, the last one is a study area that was established and equipped (weather station, three discharge gauging stations, 60 soil moisture sensors in a wireless network) by the Hydrogeology Group, TU Darmstadt.
