2. Example
A watershed has 40% residential (1/4 ac lots), 25% open space (good condition), 20% commercial and business (85% impervious) and 15% industrial (72% impervious) with corresponding soil groups of C, D, C and D.
What is the depth of runoff from 6 in of rain
Assume the rainfall occurs in a pattern of 2 in in first hour, 3 in in second hour and 1 in in third hour determine the rainfall excess hyetograph
Average slope is 3%, Area is 3 mi2, hydraulic length is 1.2 mi. Determine the SCS unit hydrograph.
What is the direct runoff hydrograph from the rain used earlier
