| Watershed Description: | 2 km^2 artificial watershed, which is formed as a V-shaped valley which is designed to represent a low mountain range. The main characteristics of the artificial catchment are representative of the 693 km^2 Dill catchment, a mesoscale low mountain range catchment situated in the south-east of the Rhenish Massif region in Germany. |
| Calibration Summary: | |
| Validation Summary: | Monthly 1990-96: E = .88 (based on simulated flows of artificial watershed vs. measured flows from Dill) |
| General Comments: | It was determined that 10,000 Monte Carlo simulations were sufficient to obtain representative distributions of model output. The authors report impacts on surface runoff, groundwater recharge, and streamflow for different hypothetical configurations of land use (land use scenarios reflect variations between forest, pasture, and cropland). |
