| Summary: | 碩士 === 國立成功大學 === 水利及海洋工程學系專班 === 94 === Drainage regulation was planned to control the flood in the past and it usually worked. But the basin is quickly urbanization and the climate changes, the peak flow becomes greater and the travel time becomes shorter than before. The drainage regulation program may not well work now. If engineers want to improve the flood problems, they must try the new way. That's comprehensive regulation program.
SOBEK model is used to obtain inundation distribution, including inundation depth and area, and to identify flood probability on San-Ye basin. According to hydraulic computations this study planned the drainage and comprehensive regulation programs to improve the flood problem. After implementation of proposed project, the hydraulic computation showed that most of reaches will avoid flood risk under the rainfall of 10 year return period.
