Question

In the storage coefficient, the unit change in the component of the head is measured in _________ to the surface.

(a) normal

(b) tangential

(c) radial

(d) inclined at 30°

This question was posed to me in homework.

I'd like to ask this question from Well Hydraulics topic in portion Well Hydraulics of Geotechnical Engineering I

Answer 1

Correct option is (a) normal

For explanation I would say: The storage coefficient is defined as the volume of water that an aquifer releases per unit surface area per unit change in the component of head normal to that surface.
