Question

When all wells do not extend through the full thickness of an aquifer, the resulting flow pattern includes

• A. Uniform flow
• B. Complex flow
• C. Reduced recharge
• D. Zero drawdown

Hint:

Well penetration: \[ \boxed{ \begin{aligned} \text{Fully penetrating well} &\rightarrow \text{Mainly horizontal flow}\\ \text{Partially penetrating well} &\rightarrow \text{Complex (3-D) flow} \end{aligned} } \]

Answer 1

The Correct Option is B

When wells partially penetrate an aquifer, groundwater flows both horizontally and vertically toward the well. This produces a three-dimensional and complex flow pattern instead of uniform horizontal flow. Hence, \[ \boxed{\text{Complex flow}} \] is the correct answer. Therefore, \[ \boxed{(B)} \]
