1. What is Aquifer Loss?

Aquifer loss refers to the reduction in hydraulic head in an aquifer due to groundwater extraction. It is calculated as the product of the aquifer loss coefficient and the discharge rate.

2. How Does the Calculator Work?

The calculator uses the aquifer loss formula:

Where:

• \( B \) — Aquifer Loss Coefficient
• \( Q \) — Discharge rate (m³/s)

Explanation: The aquifer loss represents the head loss specifically attributed to the aquifer properties and the rate of water extraction.

3. Importance of Aquifer Loss Calculation

Details: Accurate calculation of aquifer loss is essential for groundwater management, well design, and predicting the impact of pumping on aquifer systems.

4. Using the Calculator

Tips: Enter the aquifer loss coefficient and discharge rate. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the aquifer loss coefficient?
A: The aquifer loss coefficient is a constant that represents the head loss per unit discharge in the aquifer.

Q2: How is discharge rate measured?
A: Discharge rate is typically measured in cubic meters per second (m³/s) using flow meters or other measurement devices.

Q3: What factors affect aquifer loss?
A: Aquifer loss is influenced by aquifer properties such as permeability, thickness, and storage coefficient, as well as the pumping rate.

Q4: How does aquifer loss relate to well loss?
A: Total drawdown consists of aquifer loss and well loss. Aquifer loss occurs in the formation, while well loss occurs near the wellbore.

Q5: Can this calculator be used for confined and unconfined aquifers?
A: The basic formula applies to both, but the aquifer loss coefficient may differ between confined and unconfined aquifer conditions.
