  • Evaluation of the effects of flood prevention on the formation of hydrograph

抄録

The ovjective of the present study is to clarify the formation and deformation processes of hydrograph caused by the topografic configuration of basins and the various flood prevention works. Firstly we introduced the basic equation to express the behavior of flood wave in a river. We found that the equation has the same precision with the basic equations of unsteady open channel flow. Secondly we investigated the effects of Manning's coefficient and the degradate of river bed on the downstream defromation of hydrograph. Finally through numerical simulations, we evaluated the hydrological effects of the various flood preventions such as cut-off works of channels and dams.
