a. A rainfall Hyetograph (intensity Vs time) is given in the below figure The hydrograph (flow Vs time) is also given below. The index is glven as 7.5 mm/hr. Determine the total volume of runoff and th watershed area. Q1. 50.0 20.0 37.5 25.0 12.5 1 2 4. 24 Time (Hr) Time (Hr) b. Assume 500 mm of rain fell on a watershed of area 100 ha (1=10000m) in one year and if 30 % of the rainfall was lost to evapo- transpiration and the change in storage capacity was 0, calculate The average value of Q from the watershed in m seç' km2.
