Question 1 A-6 hour storm occurred over a catchment of 1.8 km2 area and the total rainfall observed was 24 cm. An infiltration capacity curve prepared had the initial infiltration capacity of 2 cm/hr and attained a constant value of 0.5 cm/hr after 3 hours of rainfall with a Harton's equation constant, k = 5 hr-¹. An IMD pan installed in the catchment indicated a decrease of 0.8 cm in the water level during 6 hours of its operation, then the runoff from the catchment is [Take pan coefficient = 0.7 and neglect other losses] cm.
