Question 2
Question 3
Over a basin of area 333 km2, there was a storm for 6 h with a uniform intensity of 2 cm/h. The observed runoff was 20×106 m3. The average rate of infiltration for the basin was
Question 4
Question 5
The infiltration capacity at the start of this event (t = 0) is 17mm/hour, which linearly decreases to 10 mm/hour after 40 minutes duration. As the event progresses, the infiltration rate further drops down linearly to attain a value of 4mm/ hour at t = 100 minutes and remains constant thereafter till the end of the storm event. The value of the infiltration index, ϕ (in mm/hour, round off to 2 decimal places), is _______
