Which of the following factors make a site more suitable for a hydroelectric dam?

A) numerous faults and fractures that allow groundwater to flow into the reservoir
B) permeable rocks next to and beneath the dam to keep pressures from building up
C) a canyon that is wide so that a large dam can be built
D) weak units in the abutments to make construction easier
E) none of these

Hydroelectric Dam

A structure built across a river to hold back water for the purpose of generating electricity through the movement of water.

Permeable Rocks

Rocks that have connected spaces or pores, allowing fluids to pass through them, critical in the study of groundwater flow and hydrocarbon reservoirs.

Faults and Fractures

Breaks in the Earth's crust where blocks of the crust have moved relative to each other due to tectonic forces.
