1. What is Aquifer Loss?

Aquifer loss is the product of discharge and aquifer loss coefficient. It represents the portion of total drawdown attributed to the aquifer's resistance to flow.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Total Drawdown in Well — The reduction in hydraulic head observed at a well in an aquifer (Meter)
• Head Loss in well — The difference between the head of the aquifer immediately outside and in the well (Meter)

Explanation: This formula separates the total drawdown into aquifer loss and well loss components, helping to analyze well performance and aquifer characteristics.

3. Importance of Aquifer Loss Calculation

Details: Calculating aquifer loss is crucial for understanding aquifer properties, well efficiency, and designing effective groundwater extraction systems. It helps in distinguishing between losses due to aquifer characteristics and losses within the well itself.

4. Using the Calculator

Tips: Enter total drawdown and head loss values in meters. Both values must be non-negative numbers. The calculator will compute the aquifer loss by subtracting head loss from total drawdown.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between aquifer loss and well loss?
A: Aquifer loss occurs due to the aquifer's resistance to flow, while well loss occurs due to flow through the well screen and inside the well casing.

Q2: Why is it important to separate aquifer loss from total drawdown?
A: Separating these losses helps in assessing well efficiency, diagnosing well problems, and understanding aquifer characteristics for better groundwater management.

Q3: What are typical values for aquifer loss?
A: Aquifer loss varies depending on aquifer properties. In efficient wells, aquifer loss typically constitutes the majority of total drawdown, while well loss should be minimal.

Q4: How can I reduce aquifer loss?
A: Aquifer loss is primarily dependent on aquifer properties and cannot be easily reduced. Proper well design and maintenance focus on minimizing well loss rather than aquifer loss.

Q5: When should this calculation be performed?
A: This calculation should be performed during aquifer tests and well performance evaluations to assess the efficiency of groundwater extraction systems.
