1. What is Depth of Water Drained Out Per Unit Area?

Depth of Water Drained out Per Unit Area represents the amount of water that drains from a unit area after accounting for consumptive use. It is a key parameter in irrigation and water management studies.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( D_d \) — Depth of Water Drained out Per Unit Area (Meter)
• \( D_i \) — Depth of Water Applied from Unit Area (Meter)
• \( C_u \) — Consumptive Use (Meter)

Explanation: This formula calculates the net water drainage by subtracting the consumptive water use from the total water applied to a unit area.

3. Importance of Calculation

Details: Accurate calculation of water drainage is crucial for efficient irrigation planning, preventing waterlogging, and maintaining optimal soil moisture conditions for crop growth.

4. Using the Calculator

Tips: Enter both Depth of Water Applied from Unit Area and Consumptive Use in meters. Ensure values are non-negative and valid for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is consumptive use in irrigation?
A: Consumptive use refers to the amount of water used by crops through evaporation and transpiration processes that is not returned to the water system.

Q2: Why is it important to calculate water drainage?
A: Calculating water drainage helps in managing irrigation efficiency, preventing soil salinity, and optimizing water resource utilization.

Q3: What units should be used for input values?
A: Both input values should be in meters to maintain consistency in the calculation.

Q4: Can this calculation be used for all soil types?
A: While the basic formula applies universally, soil characteristics may affect actual drainage patterns and should be considered in comprehensive water management plans.

Q5: How often should these calculations be performed?
A: Regular monitoring and calculation are recommended, especially during irrigation seasons, to maintain optimal soil moisture conditions.
