Question

Rate of infiltration determined by infiltrometer is less than the one determined by rainfall simulator.

(a) True

(b) False

I had been asked this question at a job interview.

The origin of the question is Ground Water through Wells and Tubewells in chapter Ground Water for Irrigation through Wells and Tubewells of Irrigation Engineering

Answer 1

The correct answer is (b) False

To explain: The rate of infiltration measured by infiltrometer is more than the infiltration rate determined by the rainfall simulator. The rate of infiltration is directly proportional to the depth of surface retention. As the depth of retention is more in infiltrometer hence the rate of infiltration is more in infiltrometer.
