WebbThe runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess. The curve number method was developed by the USDA Natural Resources Conservation Service, which was formerly called the Soil Conservation Service or SCS — the number is … Webb(USDA) Natural Resources Conservation Service (NRCS) (then named the Soil Conservation Service (SCS)) developed a method for estimating runoff from rainfall. This method also referred as the CN method [10]. The SCS curve number method is based on the water balance equation. The SCS-CN method, expressed as equation (1) below. = (𝑃−𝐼𝑎) 2
