Question 1

Infiltration capacity of soil depends upon

Question 2

Infiltration rate is always

Question 3

The rainfall during three successive 2 hour periods are 0.5, 2.8 and 1.6 cm. The surface runoff resulting from this storm is 3.2 cm. The index value of this storm is

Question 4

During a 3 hour storm event, it was observed that all abstractions other than infiltration are negligible. The rainfall was idealized as 3 one hour storms of intensity 10 mm/hr, 20 mm/hr and 10 mm/hr respectively and the infiltration was idealized as a Horton curve, f = 6.8 + 8.7 exp (- t) (f in mm/hr and t in hr). What is the effective rainfall?

Question 5

A total run-off volume of 35 x 10⁶ m³ is observed in a basin area of 300 km² during a 8h storm with a uniform intensity of 2.4 cm/h. The average infiltration rate for the basin will be ___________mm/h.

Question 6

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 _______ cm.
[Take pan coefficient = 0.7 and neglect other losses]
