Control of flood flows by flood retarding plantations were investigated through experiments and numerical simulations. In the experiments, front positions, depths and surface velocities of flood flows in floodplain with structures and flood retarding plantations were observed. A SA-FUF-2DF model (a numerical model based on Spatial Averaged Finite volume method on Unstructuredgrid using FDS technique for 2D Flood flows) has been developed and was verified against these experimental data. The model can reproduce the complex behavior of flood flows with reasonable accuracy. The experimental and numerical resuls show that flood retarding plantations are effective in reducing the flood propagation speed.
