Question

Match List-I with List-II and select the correct answer using the codes given below the lists.

$\begin{array}{cc}\text{LIST-I}& \text{LIST-II}\\ \text{A. Rainfall intensity}& \text{1. Isohyets}\\ \text{B. Rainfall excess}& \text{2. Cumulative rainfall}\\ \text{C. Rainfall averaging}& \text{3. Hyetograph}\\ \text{D. Mass curve}& \text{4. Direct runoff hydrograph}\end{array}$

• A.

  A	B	C	D
  1	3	2	4

• B.

  A	B	C	D
  3	4	1	2

• C.

  A	B	C	D
  1	2	4	3

• D.

  A	B	C	D
  3	4	2	1

Answer 1

The correct option is B

A	B	C	D
3	4	1	2

Rainfall intensity $\Rightarrow$ Hyetograph (intensity versus time curve)

Rainfall excess $\Rightarrow$ Direct runoff hydrograph

Rainfall averaging $\Rightarrow$ Isohyets (Isohyets is the line of having equal rainfall depth and used to measure the average rainfall over a catchment)

Mass curve $\Rightarrow$ Cumulative Rainfall
