Dimensionless Depth: SCS Distributions

Webbdeveloped by SCS (NRCS) from U.S. National Weather Service data as typical design storms. The distributions are associated with climatic regions. – Type I – Type IA – … The NRCS curve number is related to soil type, soil infiltration capability, land use, and the depth of the seasonal high water table. To account for different soils' ability to infiltrate, NRCS has divided soils into four hydrologic soil groups (HSGs). They are defined as follows. • HSG Group A (low runoff potential): Soils with high infiltration rates even when thoroughly wetted. These consist chiefly of deep, well-drained sands and gravels. These soils have a high ra… leaflets on anxiety
