The Rational Method equation actually used to calculate peak storm water runoff rate is: Q = CiA(U.S. units), or Q = 0.0028 CiA(S.I. units) where: •A= the area of the watershed (drainage area) that drains to the point for which the peak runoff rate is needed (acresfor U.S. units) (hafor S.I. units)

17 cze 1986 · 1. Introduction. Calculation of peak storm water runoff rate from a drainage area is often done with the Rational Method equation (Q = CiA). Use of Excel spreadsheets for calculations with this equation and for determination of the design rainfall intensity and the time of concentration of the drainage area, are included in this course.
