Model Information
For more information about this model, go to wwwbrr.cr.usgs.gov
Spatial Resolution
The model area of analysis is divided into hydrologic response units, where the HRUs are user delineated, often through GIS.
Temporal Resolution
Time step is daily, but can be more frequent. Short time steps, less than one day are considered "storm" mode.
Outputs
Model outputs include runoff predictions, flow routing of water to soil water, groundwater or stream flow. Model also performs statistical analyses, optimization and visualizations.
