WebAccording to the Rational method, the highest Qp occurs when the rainfall duration equals Tc. When the rainfall duration is greater than Tc, the Qp is reduced, but the total runoff volume is increased. The objective is to find the total duration of Tc x SDF (critical storm event) that maximizes the required storage of a detention pond. WebIn the rational method and similar runoff estimation methods such as the Wallingford Procedure Modified Rational Method, IH 124, ADAS 345 methods the time of concentration is used to determine the critical storm duration. This in turn is used to determine the design rainfall intensity for use in the rational method.
