Webb20 juli 2024 · The curve number method was developed in the 1960s by the USDA Soil Conservation Service (SCS, now the Natural Resources Conservation Service), and has … WebbThe SCS method for estimating the volume of direct runoff from storm rainfall relates the initial abstractions, and retention parameters to watershed properties as described by the curve number (CN). The potential maximum retention after runoff occurs is related to the CN as follows: S. =. Potential maximum retention after runoff begins. CN. =.
