Rational Method
RATIONAL MODEL FOR COMPUTING Q PEAK DISCHARGE FROM A WATERSHED OR SUBBASIN
Where Q = Peak discharge in cubic feet. Per second A = Area of the watershed in acres
C = Coefficient of runoff for the watershed, based on area-proportional, combined runoff coefficients for slop, land cover and
soil typesT = Concentration time (in minutes) I = Maximum rainfall intensity (in inches per hour) that can occur
during the concentration timeM = Mannings’s coefficient of roughness
Q = f ( A, C, T, I, M )
