Question

Consider the following components of hydrograph and arrange them in order from beginning of rainfall to end of rainfall in semi-arid regions:
A. Point of inflection
B. No-flow
C. Rising limb
D. Peak
E. Falling limb

• A. C, B, A, D, E
• B. B, C, D, A, E
• C. A, C, D, E, B
• D. B, C, D, E, A

Hint:

Hydrograph sequence:
No-flow \(\rightarrow\) Rising limb \(\rightarrow\) Peak \(\rightarrow\) Recession (Falling limb).
Point of inflection is on the recession curve.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
A hydrograph shows the flow of water over time after rainfall.
It has different components in sequence.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the sequence of hydrograph components.

Step 3: Detailed Explanation:
The sequence of hydrograph components from beginning of rainfall to end is:
No-flow \(\rightarrow\) Rising limb \(\rightarrow\) Peak \(\rightarrow\) Point of inflection \(\rightarrow\) Falling limb.
No-flow is the initial condition before rainfall.
Rising limb shows the increase in flow.
Peak is the maximum flow.
Point of inflection is where the rate of decrease changes.
Falling limb is the recession.
Thus, the order is B, C, D, A, E.

Step 4: Final Answer:
The correct order is B, C, D, A, E.
Hence, the correct option is (B).
