Abstract
The purpose of this study is to compare and analyze design flood estimation methods which are the basis for determining the size of a flood control structure. The result from a flood frequency analysis which is considered as the best way for estimating design flood was assumed as a true value, and a method of simulating runoff and performing frequency analysis of the maximum discharge data were compared with a design storm method. For a comparative analysis of design flood estimation, seven basins (Namgang reservoir basin, Soyanggang reservoir basin, Andong reservoir basin, Seomjingang reservoir basin, Imha reservoir basin, Chungju reservoir basin, Hapcheon reservoir basin) were selected. For the Seomjingang, Hapcheon, and Imha reservoir basins, the method proposed in this study showed better results, whereas the conventional method showed better results for the Namgang, Soyanggang, and Chungju reservoir basins. The results show that the conventional method (the design storm method) is not the best way for estimating design flood and the proposed method can be used as an alternative for small basins.
