Determine the peak discharge resulting from a 1-hour rainfall with a constant intensity equal to 1.5 × 10⁻⁵ m/s that happens on a pervious rectangular basin with the following characteristics:

L = 120 m, S = 0.002 , and n = 0.02 . The infiltration parameters are 9 = 0.414 , K = 1.5 × 10⁶ m/s, and P_f = 0.25 m. At the beginning of the rainfall, the basin soil is 0.65 % saturated.
