440 - Homework 14 (Peak Runoff)
1.
Determine the maximum runoff (20-year design storm) from a
53-acre watershed (predominantly heavy clay, flat lawns) near Stewart Intl.
Airport (IDF here) Assume the time
of concentration = 2 hours.
2.
Two adjacent fields contribute runoff to a collector whose
capacity is to be determined (see diagram).
The intensity for a 25-minute duration is 3.9
in/hr. Determine the peak runoff flow.
