AB  - Understanding the soil-vegetation-atmosphere continuum is essential to improve hydrological model predictions. Particularly the characterization and prediction of the spatio-temporal variability of soil water content (SWC) and its controlling factors are of high interest for many geoscientific fields, since these patterns influence for example the rainfall-runoff response and the partitioning of the net radiation into latent and sensible heat fluxes while interacting with the vegetation cover. Within this context, this PhD thesis explores the degree of model complexity that is necessary to adequately represent heterogeneous subsurface processes, and the benefit of merging soil moisture data with an integrated terrestrial model. This includes an uncertainty analysis of model forcing (i.e. precipitation) and evaluation data (actual evapotranspiration). On this account, the fully coupled land surface-subsurface model ParFlow-CLM, which is part of the terrestrial system modeling platform (TerrSysMP), was applied to the 38 ha Rollesbroich headwater catchment located in the Eifel (Germany). Detailed long-term data for model setup, calibration, and evaluation were provided by the TERENO infrastructure initiative, the North Rhine-Westphalian State Environment Agency, and the Transregional Collaborative Research Center 32. It was expected that this combination of process orientated model and extensive observation data contributes to the understanding of the complex processes of the energy and water cycle at the hillslope, the elementary unit for the runoff generation process. The first part compared different measurements of actual evapotranspiration (ETa) obtained by a set of six weighable lysimeters, ETa estimates acquired with the eddy covariance (EC), and evapotranspiration calculated with the full-form Penman Monteith equation (ETPM) for the Rollesbroich site. This comparison of ETa included a correction of the energy balance deficit for the EC method, which is not often reported in literature and allows a deeper insight into the performance of both methods. The evaluation was conducted for the year 2012 and showed that both measurement methods are in good agreement with a total difference of 3.8
