摘要

滯洪池爲滯洪設施中之重要項目，其作用在降低洪峰流量，控制流心及有效調節泥沙流出量。爲剖析滯洪設施中受制歷線作用下其滯洪容積變化，本文依無因次滯洪理論分析法爲基礎，以數學解析方式探討受制已知三角形入流歷線及洪峰消減程度相互影響下，滯洪池內其滯洪容積對應時間變化情形，進而推求該滯洪池之最小滯洪容積，期爲坡地開發設置滯洪設施之設計上參考。

The retarding basin is one of the crucial items in the detention facilities. It may effectively alleviate the occurrence of peak discharge control the center of flood flow, and reduce the amount of soil loss. The present study, aims to obtain the change in volume of a retarding basin under the known flow hydrograph in the detention facility. The volume change of detention, which is under the interaction of a given triangular inflow hydrograph and the extent of peak attenuation, is investigated by using the non-dimensional detention theory and the related exact analyses. The minimum detention volume of the retarding basin can therefore be calculated based on the results of change in volume of detention. The detention volume is proposed to be used for designing the detention facilities in the field of slopeland development.
