For example, the peak flows calculated from Rational Formula are used as inflow and outflow of detention pond, respectively. One hour is instead of those of less than one-hour duration. The decision of safety factor is. The triangular unit hydrograph is derived without rainfall pattern, etc. Hence, this study tries to analyze and discuss the factors of designed rainfall pattern, rainfall duration, baseline of hydrograph and to compare the detention volume calculated from SCS and Rational Formula. And, results could be as a reference of revising Handbook of Soil and Water Conservation in the future.滯洪池滯洪體積合理化公式水土保持手冊Detention pondDetention volumeRational FormulaHandbook of Soil and Water Conservation
