The AgroEcoSystem-Watershed model (AgES-W) is based on the European J2000 (J2K) modeling system (Krause, 2002; Krause et al., 2006). AgES is a modular, spatially distributed hydrological system which implements hydrological processes as encapsulated process components. AgES operates at various temporal and spatial aggregation levels throughout the watershed. For example, runoff is generated at the Hydrologic Response Unit (HRU) level with subsequent calculation of runoff concentration processes (through a lateral routing scheme) and flood routing in the stream channel network. The generation of four separate runoff components surface runoff, interflow from the unsaturated soil zone, interflow from the saturated weathering layer of the underlying hydro-geological unit, and saturated baseflow is simulated inside the modeling core of AgES for each HRU (Figure 1).
