Abstract

<p>Because the intakes of the run-off-river hydro power plants faces rivers, sediment in the riverbed flows in the waterway through the intakes when floods occurs. We developed a model to forecast sedimentation in the run-off-river hydro power plants. By this model, operators in the power plant can judge the stop of the water-intake to make damage with sedimentation a minimum.</p><p> This model is composed of three parts, the forecast of river discharge at the river by tank model, the forecast of total load at the river in front of the intake and the forecast of the ratio of sedimentation to total load in the river. Each model was constructed with results of 1-D and 2-D numerical analyses. We reproduced sedimentation of a hydraulic power plant in Okayama Prefecture from 2003 to 2008 by this model and compared the result with the observation data. This comparison showed that this model was able to reproduce the sedimentation process in this run-off-river hydro power plant</p>
