Question

Match LIST I with LIST II
\[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Artesian aquifer} & I. \ \text{Unconfined aquifer} \\ B. \ \text{Draw down curve} & II. \ \text{Confining formation} \\ C. \ \text{Well development} & III. \ \text{Cone of depression} \\ D. \ \text{Percolation well} & IV. \ \text{Compressed air} \\ \hline \end{array} \]
Choose the correct answer from the options given below:

• A. A-II, B-III, C-IV, D-I
• B. A-II, B-III, C-IV, D-I
• C. A-II, B-IV, C-I, D-III
• D. A-IV, B-I, C-III, D-II

Hint:

Groundwater keywords: - Artesian \(\rightarrow\) Confined - Drawdown \(\rightarrow\) Cone of Depression - Well Development \(\rightarrow\) Cleaning (e.g., with compressed air) - Percolation/Recharge \(\rightarrow\) Adds water to unconfined aquifers

Answer 1

The Correct Option is A

Step 1: Associate each term in LIST I with its corresponding definition in LIST II.
- A. Artesian aquifer: An aquifer covered by an impermeable layer (confining formation or aquiclude), resulting in internal pressure.
- B. Drawdown curve: A graphical representation of the water level drop around a pumped well, depicting the cone of depression.
- C. Well development: The process of clearing fine particles from a new well screen to enhance its efficiency, often employing compressed air for agitation.
- D. Percolation well: Likely a term for a recharge well or percolation tank, used for artificial recharge of an unconfined aquifer.
Step 2: List the correct pairings.
- A \(\rightarrow\) II
- B \(\rightarrow\) III
- C \(\rightarrow\) IV
- D \(\rightarrow\) I
This set of pairings matches option (A).
