Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 90 === Because of the hillside-over-development in Taiwan, the soil infiltration rate has reduced and the impervious area has increased of the watershed. In the event of a flood, this situation results in disasters within the downstream areas. It is necessary to establish flood detention facilities to delay the peak time and to reduce the peak flow. Since that computer technology has been improved so much that we make the detention facilities design, previously by hands, now by computers. In this study, the input hydrographs use isosceles trapezoid hydrograph and triangle hydrograph and gamma hydrograph in detention pond, and it uses Runge-Kutta method and Microsoft Visual Basic language to compiles a Windows-based program. In this paper, it also collects the detention facilities design data and use it to compare with the modal to help us make more accurate detention pond design in a more convenient way.
