When it rains, often more water hits the earth than can be absorbed by the ground the excess water, called surface runoff, drifts into sewers or drains. Hello this is steve regan of the modeling of watershed systems group this presentation describes the surface runoff modules srunoff_carea and srunoff_smidx this cartoon illustrates flow paths in the hydrologic cycle. The rational method is a commonly used procedure for estimating the peak surface runoff rate from an urban watershed for use in design of storm water management facilities, such as storm sewers, storm water inlets, and storm water detention ponds. Surface runoff surface runoff occurs when rainfall exceeds a soil's maximum saturation level and all surface depressional storage is filled to capacity the rate of runoff flow depends on the ratio of rain intensity to the infiltration rate.
