In this study, the hydraulic channel routing model is applied to analyze water surface elevation pattern on the Nakdong river in flood cases. The procedure to apply FLDWAV model is presented to solve the Saint-Venant Equations by using four points implicit finite differential scheme. And the flood travel time is studied for reasonable dam management. As this results, variable assumption and constraint are followed to evaluate flood travelling time by hydraulic model. A guideline of reasonable dam's decision making considering downstream effect is showed by this constructed model, and scientific hydraulic analysis is possible by it.
