Description	Other Transformation process of flood waves and hydraulic characteristics of unsteady flows were investigated experimentally in compound channels with locally vegetated flood plains. Some noticeable differences between unsteady flow structure in compound channels with and without vegetation were revealed. The shortly vegetated zone in the flood plains causes the sharp decrease of the flow depth in front of that and increases the upstream stage extremely. 2-D depth-averaged numerical calculation technique for unsteady flow with vegetation in flood plains was developed. The calculated results reproduce well the characteristic tendency of the experiments. This calculation method is useful for the flood routing passing such a complex flow field.
