The composite runoff coefficient is the weighted average of all of the land uses within the drainage area. Note that our rational equation calculator allows you to use a variety of units. Enter coefficient, intensity, and area to estimate peak discharge. \ ( i \) is the rainfall intensity in mm/hour for the design return period and for a duration equal to the “time of concentration”.
