Description
This 5-kilometer resolution raster (grid) dataset for the conterminous United States represents the
average percentage of infiltration-excess overland flow in total streamflow estimated by the watershed
model TOPMODEL. Infiltration-excess overland flow is simulated in TOPMODEL as precipitation that
exceeds the infiltration capacity of the soil and enters the stream channel.
TOPMODEL was applied to 5- by 5-kilometer areas across the conterminous United States using
national climate, soils, and terrain geographic information system (GIS) datasets. The model was
run for 1,000 days for each 5- by 5-kilometer area. The average percentage of infiltration-excess
overland flow in total streamflow was computed for the 1,000-day simulation in each grid cell.
