Runoff curve numbers (also referred to as curve numbers or simply CN) are empirical parameters that are commonly used in hydrology for estimating runoff volumes from rainfall excess. The curve number method was developed by the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service or SCS). hotel and flight deals to vegas
