A small water shed consists of 1.5 km2 of cultivated area (c=0.20), 2.5 km² under forest (c = 0.10) and 1.0 km² under gross cover (c= 0.35). There is a fall of 22 m in a water course of length 1.8 km. The intensity frequency duration relation for area is given by 8070.2 I= (t+13)0.46 Where I is in cms/hr, T, in years and t is in minimum. Estimate the peak rate of run off for a 25 year frequency.
