A small catchment area 300 km2received a rainfall of 15cm in 1 hour, due to a storm draining thecatchment was dry before the storm and experienced a runoff lasting for 5 hours with an averagedischarge Value of 3 m3/sec. The stream was given dry after the runoff event.(a) What is the amount of water in cm3 which was not available to runoff alone to combined effectof infiltration, evaporation and transpiration.(b) What is the ratio of total and direct runoff to precipitation.
A rainfall hyetograph is provided for a 6-hour storm event, which occurred over a watershed with an area of 2100-acres (Ac). If the Phi-index is 0.71 in/hr, calculate the volume of runoff (VRO) from the storm (in Ac-ft). Report your answer to the nearest tenths (0.1) place.
