The design storm for a basin has the depth of rainfall for successive hours as 5.6, 7.6 and 5.2 cm. The 1-hr design unit hydrograph for the basin may be approximated by a triangle of base 6 hours with a peak of 60 cumec occurring at the 2nd hour from the beginning. Compute the flood hydrograph assuming an average loss rate of 0.5 cm/hr. Base flow may be neglected.
