Question

Match List-I with List-II

Choose the correct answer from the options given below:

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

Hint:

Remember:
- "Hyeto" means rain (Hyetograph = Rain vs time).
- "Hydro" means water flow (Hydrograph = River flow vs time).
- "Mass curve" always plots cumulative or accumulated values against time.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
We match various hydrological plots, charts, and curves with their precise coordinate definitions of input variables versus time or percentage frequency.

Step 3: Detailed Explanation:
Let us review the definition of each hydrological curve:
1.

Rainfall intensity vs time (A): Known as a

Hyetograph, which represents a bar chart of rainfall intensity over time. Matches with

(II).
2.

Cumulative discharge vs time in chronological order (B): Known as a

Flow mass curve, which is used to design reservoir storage capacities. Matches with

(V).
3.

Accumulated precipitation vs time in chronological order (C): Known as a

Mass curve of rainfall. Matches with

(IV).
4.

Stream flow vs time in chronological order (D): Known as a

Hydrograph, which shows discharge variation at a specific river section. Matches with

(I).
5.

Stream discharge vs percent time (E): Known as a

Flow duration curve, which shows the percentage of time a specific discharge is equalled or exceeded. Matches with

(III).
This yields the sequence: (A) - (II), (B) - (V), (C) - (IV), (D) - (I), (E) - (III).

Step 4: Final Answer:
The correct option is 4, which corresponds to (A) - (II), (B) - (V), (C) - (IV), (D) - (I), (E) - (III).
