Determine the design discharge at a bridge site by Rational method. The data given are
Catchment area = 2000 km2
Distance of site from farthest point = 16 km
Elevation difference between critical point & the bridge site = 96 m
Peak intensity of rainfall = 60 mm/hr
Time of concentration = 4.6 hours
Consider surface of catchment is clayey and largely cultivated.(Take C = 0.5 & f =0.6)
