Q- A catchment area of 65 Sq. Km. in Gilgit received a rainfall of 12 cm from a 3-hours storm. At the outlet of the catchment, a natural stream had a steady flow of 10 cumecs before the storm and experienced a runoff lasting for 20 hours with an average discharge value of 90 cumecs. The stream was again to its original steady state with a flow of 10 cumecs. Estimate the losses and ratio of runoff to precipitation.
please show steps and explain If the rainfall excess consists of two bursts of 3.3 in./hr and 1.8 in./hrs, each for 20 minutes, and the 20-minute UH (1”) hasordinates of 15, 40, 25, and 10 ft3/s, compute the distribution of direct runoff.
