Because the intake of the run-off-river hydro power plant faces the river, gravel in the riverbed flows in the waterway through intake when the flood occurs. At a very large-scale flood, power generation stops because of the inflow of this gravel. In addition, it is necessary to remove gravel in the waterway after the flood and cost damage is caused by the inflow of this gravel. We reproduced this phenomenon in the numerical analysis, examined measures of this problem. We reproduced this phenomenon at the typhoon by using 2-dimensional numerical analysis and compared the analytical result with the observed value. We researched measures against the problem by this numerical model, clarified that measures to stop the intake are more effective than measures to add new sand flush gate.
