Question

Match List - I (Well hydraulics parameters) with List - II (Definition) and select the correct answer using the codes given below the lists:
List-I
A. Specific yield
B. Safe yield
C. Specific capacity
D. Field capacity

List-II
1. Discharge per unit drawdown of well
2. Same as specific retention
3. Measure of water that can be removed by pumping
4. Limit of withdrawal from well without depletion of the aquifer
5. Water-bearing capacity of aquifer

• A. A-4, B-3, C-2, D-5
• B. A-3, B-4, C-1, D-2
• C. A-4, B-3, C-1, D-2
• D. A-3, B-4, C-2, D-5

Answer 1

The correct option is B A-3, B-4, C-1, D-2

The quantity of water retained by the material against the pull of gravity is called specific retention or field capacity.

The quantity of water drained by the gravity to the total amount of medium drained is called specific yield.

Specific capacity of well is defined as rate of flow through it per unit drawdown.
