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. HINT...the answer should be around the 500-1,500 Ac-ft range (yes, it is a big range if you need to guess). Intensity (in/hr) 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 Time (hr) 5 6 7 2

Q2. Two storms having duration of 4-hv and 2.hr respectively. If the rainfall excess values for the two storms were 2cm f 3cm respectively occurs Successive calculate the resulting direct runoff hydrographif the 2-hr UH For the Catchment is given below Time hr 2 4 G 10 12 14 16 18 2hr UH 25 50 75 125 100 60 20
