Calculate the SWM-IV overland flow time to equilibrium for the lot of Problem 1 and compare it with the Kirpich time of concentration for the lot. Should these be equal?
Problem 1
A sloping, concrete parking lot experiences rain at a rate of 3.0 in./hr for 60 min. The lot is 500 ft deep and has a slope of 0.0001 ft/ft. If the water detention on the lot is zero at the start of the storm, calculate the complete overland flow hydrograph for 1 ft of width using the SWM-IV equations. Use a 5-min routing interval and continue computations until all the detained water is discharged.
