Question

Given below are two statements
Statement I: In surface irrigation, the advance phase is the time required for water to advance from the inlet to the outlet of the field.
Statement II: The depletion phase is the time required for water to remain on the field after the advance phase is completed.
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Hint:

Surface irrigation phases:
1. Advance: Water moving down the field.
2. Storage: Water ponding on the field.
3. Recession: Water disappearing from the surface.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
This question tests knowledge of surface irrigation phases.

Step 2: Detailed Explanation:
Surface irrigation has three phases:
1. Advance phase
2. Storage (or ponding) phase
3. Recession (or depletion) phase
Statement I:
The advance phase is the time required for water to advance from the inlet to the outlet (or end) of the field.
This is correct.
Statement II:
The depletion phase is the time required for water to disappear from the soil surface after irrigation.
It is not the time water remains on the field after advance.
The storage phase is the time water remains on the field.
This statement is false.

Step 3: Final Answer:
Thus, Statement I is true but Statement II is false.
