Measured monthly water and sediment yields can be input by the user. The model will make a statistical comparison on the measured and predicted values. The usefulness of ponds or reservoirs to trap sediment at the subbasin or the watershed outlet can be determined. Run-time graphics allow the operator to see selected processes being graphed as the model is executing. Eight graphs can be displayed on the screen simultaneously.
Input is in English or metric units.
The user documentation does not provide complete, easy to follow guidance on the UTIL program, UTIL commands, software loading, and model execution. Organic waste applications are not modeled. As nutrients and pesticides flow from each subbasin to the basin outlet, no degradation occurs. Hydraulic residence time is not considered by the lake water quality module. Output is in metric units.
