Watershed Description:
fiogf49gjkf0d
692 km^2 Dill (state of Hessen, Germany) 
Calibration Summary:
fiogf49gjkf0d
Daily (May 2000 - April 2001): sediment E = .56 total P E = .46 nitrate E = .26 
Validation Summary:Daily (May 2001 - March 2001): sediment E = .74 total P E = .77 nitrate E = .09 
General Comments:Initial flow calibration and validation was carried out on 3? Subwatersheds, and then on entire watershed. Graphical results show that the model mirrored measured trends well for flow and pollutants. The Proland agric. Econ. Model was used to generate 8 land use scenarios based on an average crop? field size (ranging from 0.5 to 20 ha). Sediment changed little while nitrate losses increased with increasing subarea size.
