The
SCS curve numbers for pre- and post-development conditions of a 54-acre
watershed are 72 and 82, respectively. The pre- and post-development times of
concentration are 50 and 35 min, respectively. Assuming a 50-yr return period
and the IDF curve of Figure 4-4, estimate the depth (in.) and volume (acre-ft)
of detention storage using the loss-of-natural-storage method. Use the SCS
rainfall-runoff equation to estimate depths of runoff.
