The model is able to reproduce runoff in a spatially realistic manner based on topography, land use and soil type. The general hydrologic trends seem to be well captured by the model. The animation shown on the right presents the spatial pattern of surface water flow over a characteristic period of three weeks at the end of 1990. The model uses interpolated data from these stations to cover the Hunting Creek area. Data are available for 1980-96.
Calibration results for the gaging station in the Hunting Creek subwatershed.
Therefore we cannot distinguish between a downpour and a drizzle if the total amount of rainfall delivered over one day is the same. The runoff associated with these events can in fact be quite different. We do not have a climatic station located directly on the watershed. Therefore we use interpolated data from two stations nearby. However some rainfall events can be very local and therefore will not be properly simulated.
