Question:
Statement I: A surface irrigation event is composed of four phases namely, advance phase, storage phase, depletion phase and recession phase.
Statement II: In recession phase of surface irrigation, the depth of water applied to any point in the field is a function of opportunity time, length of time for which water is present on soil surface.
In light of the above statements, choose the correct answer from the options given below:

In light of the above statements, choose the correct answer from the options given below:
Show Hint
Surface irrigation phases:
Advance \(\rightarrow\) Storage \(\rightarrow\) Depletion \(\rightarrow\) Recession.
Opportunity time determines infiltration.
Advance \(\rightarrow\) Storage \(\rightarrow\) Depletion \(\rightarrow\) Recession.
Opportunity time determines infiltration.

- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Surface irrigation has different phases.
Each phase has specific characteristics.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the phases of surface irrigation.
Step 3: Detailed Explanation:
Statement I: The four phases are advance, storage, depletion, and recession.
This is correct.
Statement II: In recession phase, the depth of water applied depends on opportunity time.
Opportunity time is the length of time water is present on the soil surface.
This is also correct.
Thus, both statements are true.
Step 4: Final Answer:
Both Statement I and Statement II are true.
Hence, the correct option is (A).
