Model: | SWAT |
Broad Application Category: | hydrologic only |
Primary Application Category: | DEM data resolution effects |
Secondary Application Category: | hydrologic assessment |
Watershed Description: | 250 km^2 Broadhead River, located in New Jersey, U.S. |
Calibration Summary: | |
Validation Summary: | |
General Comments: | Short paper that describes a limited assessment of DEM resolution effects on SWAT output: 1:24,000 & 1:250,000 USGS DEMs were analyzed; a flatter topography due to the 1:250,000 DEM results in delayed streamflow and less runoff volume. |
