![A 24 hour storm occurred over a catchment of
2
1.5 km area and the total rainfall observed was
10 cm. An infiltration capacity curve prepared
had the initial infiltration capacity of 1 cm/hr and
attained a constant value of 0.3 cm/hr after 15
hours of rainfall with a Horton's constant k =
5/hr. An evaporation pan installed in the
catchment indicated a decrease of 0.5 cm in the
water level (after allowing for rainfall) during 24
hours of its operation. Other losses were found to
be negligible. Determine the runoff from the
catchment area. Assume a pan coefficient of 0.65.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F87bdb7c6-be78-4d8a-bc29-d49ee4fd1b3f%2F383caace-7163-4156-8ea2-4436d2c81283%2F7046w8_processed.jpeg&w=3840&q=75)
