Question

The drawdown, corresponding to a steady discharge, are observed at a number of wells in _______

(a) pumping out test

(b) pumping in test

(c) constant head permeability test

(d) falling head permeability test

I had been asked this question in an internship interview.

The origin of the question is Well Hydraulics topic in section Well Hydraulics of Geotechnical Engineering I

Answer 1

Correct choice is (a) pumping out test

The explanation: The permeability can be determined by pumping out test. Pumping must continue at a uniform rate for a sufficient time to approach a steady state condition.
