1. A drainage basin located in the Atlanta, Georgia area has a time of concentration of 2.5 hours. Find the rainfall intensity, i, for use in the Rational Method for a 10-year storm.

2. Compute the peak runoff, Q_p, for the drainage area in problem 11 for a 50-year storm. Express Q_p
in (a) cfs and (b) m³/s.

Note: In the Arizona I-D-F curves, the P1 value corresponding to a 50-year storm is 2.25 inches.
