WebA curve number (CN) is a hydrologic parameter used to describe the stormwater runoff potential for the drainage area. It is a function of land use, soil type, and soil moisture. The Natural Resources Conservation Service (NRCS) has divided soils into four hydrologic soil groups (i.e., A, B, C, and D) according to water’s ability to infiltrate.
