Question
Rainfall intensity of a rural catchment is 50 mm/hr. The percentage contributions of catchment relief, catchment storage and ground characteristics in the calculation of runoff coefficient are 0, 5 and 30 respectively. What is the value of the S0-year ARI runoff coefficient (C) of this catchment? Write your answer correct to two decimal place.
Expert Solution
Step 1: Introduce the given data
Rainfall intensity of a rural catchment is 50 mm/hr
Contributions of catchment relief=0%
Contributions of catchment storage=5%
Contributions of ground characteristics=30%
