The NRCS Curve Number methods are the second most commonly used post-fire runoff estimation method by BAER team members (Foltz and others 2008).. The Curve Number method was developed by the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), formerly the Soil … 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… otr live cincinnati nightclub
