Compute the runoff from 5 inches of rainfall on a 1000-acre watershed. The hydrologic soil group is 50 percent Group B and 50 percent Group C interspersed throughout the watershed. Antecedent moisture condition II is assumed. The land use is given below followed by the reference table for Runoff CNs.
Only b part
. (a) Compute the runoff from a 7-in rainfall on a 1500-acre watershed that has hydrologic
soil groups that are 40 percent group A, 40 percent group B, and 20 percent group C
interspersed throughout the watershed. The land use is 90 percent residential area that is
30 percent impervious, and 10 percent paved roads with curbs. Assume AMC II
conditions.
(b) What was the runoff for the same watershed and same rainfall before development
occurred? The land use prior to development was pasture and range land in poor condition.
