The fastest groundwater flows would be expected for an aquifer with .
A) high porosity and many small pores
B) high specific retention and low permeability
C) low gradients and low permeability with a few very large pores
D) high gradients (hydraulic head) and high permeability

Question

Quizplus · Accepted Answer

The fastest groundwater flows occur in aquifers with high gradients (hydraulic head) and high permeability, as these conditions facilitate the easy and rapid movement of water through the aquifer material. High gradients increase the driving force for water flow, while high permeability indicates that the material has large, well-connected pores allowing for efficient water passage.
