Question:
Water requirement satisfaction index (WRSI) can be computed using the information on seasonal actual evapotranspiration (AET) and seasonal crop water requirement.
Water requirement satisfaction index (WRSI) can be computed using the information on seasonal actual evapotranspiration (AET) and seasonal crop water requirement.
Show Hint
WRSI = (AET WR) \(\times\) 100.
Used in drought assessment.
Higher value indicates better water availability.

- WRSI = AET WR \(\times\) 100
- WRSI = (AET \(\times\) WR) 100
- WRSI = WR AET \(\times\) 100
- WRSI = (WR - AET) WR \(\times\) 100
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
WRSI is a measure of how well crop water requirement is satisfied.
It is expressed as a percentage.
Step 2: Key Formula or Approach:
WRSI = (Actual evapotranspiration Water requirement) \(\times\) 100.
Step 3: Detailed Explanation:
The Water Requirement Satisfaction Index is the ratio of AET to WR.
It indicates the percentage of water requirement that is met.
Higher WRSI means better water satisfaction.
Thus, WRSI = AET WR \(\times\) 100.
Step 4: Final Answer:
WRSI = AET WR \(\times\) 100.
Hence, the correct option is (A).
