Question Statement:
Match the aquifer properties in Column I with the terms in Column II:
| Column I | Column II |
|---|---|
| P. Properties of confined & semi-confined aquifers | 1. Perched aquifer |
| Q. Property of an unconfined aquifer | 2. Coefficient of storage |
| R. Property of semi-confined aquifer | 3. Specific yield |
| S. Special case of an unconfined aquifer | 4. Leakage factor |
Options:
(A) P-3,Q-2,R-1,S-4
(B) P-2,Q-3,R-1,S-4
(C) P-2,Q-3,R-4,S-1
(D) P-3,Q-2,R-4,S-1
Official Answer Key:
C
Step-by-Step Solution & Explanation
Confined/semi-confined aquifers are characterized by the coefficient of storage (2). Unconfined aquifers are characterized by specific yield (3). Semi-confined (leaky) aquifers are characterized by a leakage factor (4). A perched aquifer is a special (localized) case of an unconfined aquifer, sitting above a local impermeable layer (1).
