Determine the peak discharge that will occur for the conditions indicated in Problem 16-11 if the drainage area is 0.67 mi2, and the time of concentration is 1.4 hours.
What will be an ideal response?
From Problem 16-10, the depth was found to be h = 8.38 inches.
From Figure 16.5, for a time concentration of 1.4 hours:
q'p = 260 ft3/sec/mi2/in
Determine the peak discharge using Equation 16.6.
qp = q'p (A)(h)
qp = (260)(0.67)(8.38)
qp = 1459.8 ft3/sec
Therefore, the peak discharge that will occur will be approximately 1500 ft3/sec.
