The ratio of average depth of water stored in root zone soil depth during irrigation to the water diverted from the reservoir is known as:
The ratio of average depth of water stored in root zone soil depth during irrigation to the water diverted from the reservoir is known as:
Show Hint
Project efficiency = Water stored in root zone Water diverted from reservoir.
It includes conveyance and application losses.
Overall efficiency of the irrigation project.
It includes conveyance and application losses.
Overall efficiency of the irrigation project.

- Operational efficiency
- Project efficiency
- Water convergence efficiency
- Reservoir detention factor
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Various efficiencies are used in irrigation projects.
We need to identify the specific efficiency.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the definitions of irrigation efficiencies.
Step 3: Detailed Explanation:
Project efficiency is the ratio of water stored in the root zone to water diverted from the reservoir.
It includes all losses from the reservoir to the field.
Operational efficiency is a component of project efficiency.
Water convergence efficiency is a term used in canal systems.
Reservoir detention factor is not a standard term.
Thus, the correct term is project efficiency.
Step 4: Final Answer:
The ratio is known as project efficiency.
Hence, the correct option is (B).
