Question

Match List I with List II

Choose the correct answer from the options given below:

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

Hint:

Permeability $\rightarrow$ Ability to transmit fluid; Specific Retention $\rightarrow$ Water retained; Specific Yield $\rightarrow$ Water drained; Transmissivity $\rightarrow$ Rate through unit width ($T = Kb$).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Hydrogeological parameters define the transmission and storage properties of saturated water-bearing porous geological formations.
Key Formula or Approach:
\[ T = K \cdot b, \quad S_y + S_r = n \text{ (Total Porosity)} \]

Step 2: Detailed Explanation:
Matching the aquifer properties in List I with their standard definitions in List II:
- A. Permeability (Hydraulic Conductivity): The intrinsic ability of a porous material to transmit fluid such as water (III).
- B. Specific retention (\(S_r\)): The ratio of the volume of water a porous material retains against gravity drainage to its total bulk volume (IV).
- C. Specific yield (\(S_y\)): The ratio of the volume of water that will drain under gravity to the total bulk volume of the formation (II).
- D. Transmissivity (\(T\)): The rate at which water is transmitted through the entire saturated thickness and unit width of the aquifer under a unit hydraulic gradient (I).
Thus, the correct matching sequence is A-III, B-IV, C-II, D-I.

Step 3: Final Answer:
Hence, the correct matching is A-III, B-IV, C-II, D-I, corresponding to option (D).
