Abstract
The Saba River in Yamaguchi Prefecture has many weirs and it induces a flood control problem due to breaking the continuity of water and sediment. The removal and integration of weirs have been executed in the Saba River. It is important to know the influence of the weir removal on the river bed deformation in the downstream area.<br>The purpose of this study is to estimate the sediment movement and river bed deformation due to the removal and integration of weir using two-dimensional numerical simulation. The results of numerical simulation indicate that two-dimensional simulation considering the effects of vegetation to the water flow is useful and the river bed deformation is to be complicated with progress of the time.
