Two-dimensional numerical analysis for a steep urban river, in which several sloping channels with energy dissipators are placed, were conducted to examine the flood control characteristic of the river. Firstly, experiments of the scale down model of the river were conducted to observe the depth as well as velocity of the flow. A two-dimensional numerical model, based on finite-volume method with unstructured grid system and flux-difference splitting, was applied to the model river and verified through these experimental data. Secondary, the model is applied to the river and the places where inundation and erosion in the river bed and bank possibly may be suffered, were identified. It is demonstrated that the model is a useful tool for river improvement of a river with complex channel geometry.
