Question

Match List I with List II

List I & List II
A. \(\Phi\)-index & I. Short-term storage and lost by evaporation
B. Detention storage & II. Rating curve
C. Current meter & III. Infiltration index
D. Stage-discharge relationship & IV. Velocity measurement

Choose the correct answer from the options given below:

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

Hint:

\(\Phi\)-index: infiltration index.
Detention storage: surface storage.
Current meter: velocity measurement.
Rating curve: stage-discharge relationship.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
We need to match hydrological terms with their definitions.
These are related to rainfall-runoff relationships.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the definitions.

Step 3: Detailed Explanation:
\(\Phi\)-index is an infiltration index (A-III).
Detention storage is short-term storage lost by evaporation (B-I).
Current meter is used for velocity measurement (C-IV).
Stage-discharge relationship is the rating curve (D-II).
Thus, A-III, B-I, C-IV, D-II is the correct matching.

Step 4: Final Answer:
The correct matching is A-III, B-I, C-IV, D-II.
Hence, the correct option is (A).
