| This paper presents a methodology for the calculation of effective rainfall by the SCS method using 3-dimensional digital elevation map and a Triangular Irregular Network module. The effective rainfall is calculated by taking into the increases of the runoff curve number(2%, 3%) due to the 10% increases of the slope of hillside, and the result indicate that the effective rainfall varies 5.0%¡12.0% with the storm events. It is demonstrated that in case of using the SCS method for the calculation of effective rainfall in the mountainous watershed with great elevation difference, the methodology taking into the slope of hillside is more viable. |
