1. What Is Total Irrigation Water Depth Applied?

Total Irrigation Water Depth Applied (D_i) represents the total depth of water applied to a unit area of land through irrigation. It is the sum of the water consumed by the crops (Consumptive Use) and the water that drains out from the unit area.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( D_i \) — Total Irrigation Water Depth Applied (m)
• \( C_u \) — Consumptive Use (m)
• \( D_d \) — Depth of Water Drained out Per Unit Area (m)

Explanation: This formula calculates the total amount of irrigation water applied by adding the water consumed by the crops and the water that drains away from the irrigated area.

3. Importance Of Irrigation Water Depth Calculation

Details: Accurate calculation of irrigation water depth is crucial for efficient water management in agriculture. It helps in planning irrigation schedules, optimizing water use, and ensuring sustainable farming practices.

4. Using The Calculator

Tips: Enter the Consumptive Use and Depth of Water Drained out Per Unit Area in meters. Both values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is Consumptive Use?
A: Consumptive Use refers to the amount of water used by crops for transpiration and evaporation, which is not available for reuse in the same system.

Q2: What does Depth of Water Drained out Per Unit Area represent?
A: It represents the amount of water that drains away from the irrigated area, which may include runoff and deep percolation.

Q3: Why is it important to calculate Total Irrigation Water Depth Applied?
A: It helps in assessing the efficiency of irrigation practices and in making informed decisions for water conservation and crop management.

Q4: Can this calculator be used for all types of crops?
A: Yes, the formula is general and can be applied to any crop, but the values of Consumptive Use and drainage may vary.

Q5: How can I improve irrigation efficiency based on this calculation?
A: By minimizing drainage losses and optimizing Consumptive Use through better irrigation scheduling and techniques.
