This basically replaces the rational method with user defined flows.

Webb3.1. SCS Hydrologic Method * The SCS hydrologic method requires basic data similar to the Rational Method: drainage area, a runoff factor, time of concentration, and rainfall. However, the SCS approach is more sophisticated in that it also considers the time distribution of the rainfall, the initial rainfall losses due to interception and depression … Webb7 apr. 2024 · The NRCS-CN method, formerly known as the SCS-CN, often used for estimating runoff at the watershed scale, developed in 1954 and published by the original Soil Conservation Service in Section 4 of the National Engineering Handbook (NEH-4), relies on a single parameter referred to as the CN, which is derived from the runoff-producing … su nova -s /bin/sh -c nova-manage api_db syncWebbGroup C Soils: Low infiltration (moderate to high runoff).
