Runoff Coefficients

The runoff coefficient is a function of the ground cover and the rainfall intensity. During a storm the actual runoff coefficient increases as the soil become saturated. The greater the rainfall intensity, the greater is the runoff coefficient due to the reducing relative amount of rainfall losses.


Recommended values of C may be obtained from Design Chart 14.3 (MSMA,2000) for urban areas and Design Chart 14.4 (MSMA,2000) for rural areas.
