Primary Application Category: | sediment loss and transport |
Secondary Application Category: | calibration, sensitivity, and/or uncertainty analysis |
Watershed Description: | 692 km^2 Dill River and 820 km^2 Dijle River, located respectively in the State of Hessen in Germany and in central Belgium. |
Calibration Summary: | Daily (Oct. 98 - April 2000; Dilje) sediment r2/E (old) = .29/.02 sediment r2/E (new) = .71/.45 |
Validation Summary: | Daily (June 2000 - July 2001; Dill) sediment r2/E (old) = .41/-.93 sediment r2/E (new) = .81/.57 |
General Comments: | Modified Sediment delivery approach is introduced that accounts for distance between the source areas and streams. The new approach replicated sediment loss much more accurately that the old approach (used in the standard SWAT model). Graphical results are shown; no flow results are reported. |
