http://zonums.com/online/hydrology/curve_number.php?id=1 WebbUS SCS Model. The SCS method is a widely accepted model for predicting storm flow volumes from rural catchments. The method is used in the USA, France, Germany, Australia and parts of Africa. It was derived for rural catchments with uniform conditions. Although some engineers have used it on urban catchments, this is not its correct application.
