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.
