Question

Which among the following need not be given prime importance during geological investigation?

(a) Groundwater conditions

(b) Wind conditions

(c) Structural constitution

(d) Trend and rate of weathering

I have been asked this question in an online quiz.

The above asked question is from Geological Investigations and Silting topic in section Dams and Reservoirs of Engineering Geology

Answer 1

The correct option is (b) Wind conditions

To explain I would say: Since reservoirs are essentially water storage basins, the area should possess such geological characteristics that favour holding of water in the basin so created. Such characters are: topographic suitability, ground water conditions, permeability and structural stability and also trend and rate of weathering.
