A 3hr storm had 9cm of rainfall and the resulting direct runoff was 3.0 cm. If the – index remains at the same value, the runoff due to 14 cm of rainfall in 5hr in the catchment is
The infiltration capacity of soil in a small watershed was found to be 8cm/hr before a rainfall event. It was found to be 1.5cm/hr at the end of 10 hrs of storm. If the total infiltration during 10 hr period of storm was 22.5cm. Estimate the value of decay coefficient k in horton’s infiltration capacity equation.
The intensity of rainfall for successive 1 hour period of a 5 hours storm are 3, 5, 7, 8 and 4 cm/hr. the runoff is 4 cm/hr. Calculate the – index (cm/hr).
Question 4Multiple Correct Options
The infiltration capacity of an area depends on which of the following factors?
Question 5Multiple Correct Options
Following are the observations during a 3hr storm
Rainfall intensity is constant throughout the respective duration. If the infiltration rate given by Horton equation is f = 9 + 16.31 e-t. Which of the following are true?
If a rainstorm of 8 cm gives the runoff of 4 cm in a catchment whose -index is fixed and for whole period of 3 hrs of rainfall. If the infiltration is considered invariable then what would be the runoff (in cm) for 10 cm of rainfall in the same catchment in 4.5 hours?
