| Summary | We have first classified small to medium rivers into several types by topography of river to predict the qualitative responses of river channel to river works. For detailed analysis, we have proposed a simple calculation method on river bed variation considering the change of vegetation area and its effect on sediment deposition. We also analyzed the effect on flood flow caused by river works for several types of catchment. Based on these results, we proposed a framework of river channel planning and design considering the change on flood and environment after river improvement. |
