... HydroGeoSphere was applied to the forested Wüstebach basin (27 ha) to simulate water fluxes. The fully coupled flow simulation model was applied to the headwater catchment at two different spatial resolutions (25 and 100 m). The change in spatial resolution required an aggregation of the soil map, which...

..., a detailed water balance was calculated using a coupled surface–subsurface hydrological model (HydroGeoSphere). In a first step, the model was parameterized with detailed runoff and soil water content data collected during simulated rainfall to calibrate surface and subsurface flow processes simultaneously...

... database ( Soil Survey Staff, 2014 ). HydroGeoSphere is a physically based, integrated surface–subsurface flow software applied to simulate a hydrologic response in heterogeneous vertical soil columns. HydroGeoSphere takes into account key components of the water cycle, solving surface...

... to be more mathematically accurate. To better understand and represent the disparate timescales inherent in the surface–subsurface systems, Park et al. (2009) present an implicit, adaptive, time-integration scheme for a fully integrated model (HydroGeoSphere). They use this scheme to decouple the time...
