WebStandard Rational The Standard Rational method computes the peak discharge as determined by the well-known Rational formula. Where: Qp = peak discharge, cfs (cms) k = 1 English (0.00278 Metric) C = runoff coefficient A = basin area, acres (hectares) i = intensity, in/hr (mm/hr) Cf = frequency correction factor where C x Cf <= 1.0 Webcalculating peak discharge. The Modified Curve Number Method is DEQ’s preferred way to calculate the peak discharge for the water quality treatment volume associated with the BMP drainage area. The method is based on the Small Storm Hydrology Method (Pitt, 1999) and Natural Resources Conservation Service (NRCS) Graphical Peak Discharge Method in
