Question

Match List-I with List-II

List-I	List-II
(A) Hydrograph	(III) Discharge vs time
(B) Mass curve	(I) Cumulative rainfall vs time
(C) Double mass curve	(II) Cumulative rainfall of nearby station vs cumulative rainfall of concerned station
(D) Hyetograph	(IV) Rainfall intensity vs time

Choose the correct answer from the options given below:

• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• (A) - (III), (B) - (I), (C) - (II), (D) - (IV)

Hint:

A hydrograph represents discharge over time, while a hyetograph represents rainfall intensity over time.

Answer 1

The Correct Option is A

Step 1: Graph Interpretations.
- (A) Hydrograph: Displays discharge over time; corresponds to (III) Discharge vs time.
- (B) Mass curve: Shows cumulative rainfall over time; corresponds to (II) Cumulative rainfall of nearby station vs Cumulative rainfall of concerned station.
- (C) Double mass curve: Relates cumulative rainfall to another station's cumulative rainfall; corresponds to (I) Cumulative rainfall vs time.
- (D) Hyetograph: Represents rainfall intensity over time; corresponds to (IV) Rainfall intensity vs time.

Step 2: Conclusion.
Therefore, the correct match is: (A) - (III), (B) - (II), (C) - (I), (D) - (IV), making option (1) the correct answer.

Final Answer: \[ \boxed{1. \, (A) - (III), (B) - (II), (C) - (I), (D) - (IV)} \]
