1. What is the Area of Well Calculation?

The Area of Well calculation determines the land area around a well that is influenced by pumping, based on yield from an open well, specific capacity, and depression head.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — Area of the Well (m²)
• \( QY \) — Yield from an Open Well (m³/s)
• \( K_s \) — Specific Capacity
• \( H \) — Depression Head (m)

Explanation: This formula calculates the area influenced by well pumping by dividing the yield by the product of specific capacity and depression head.

3. Importance of Area Calculation

Details: Calculating the area of influence is crucial for understanding the extent of groundwater drawdown, managing well interference, and planning sustainable water extraction.

4. Using the Calculator

Tips: Enter yield in m³/s, specific capacity, and depression head in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the Area of the Well?
A: The Area of the Well refers to the land area around a well that is influenced by pumping activities.

Q2: What is Yield from an Open Well?
A: Yield from an Open Well is the flow discharge into the well under a specific depression head.

Q3: What is Specific Capacity?
A: Specific Capacity is the amount of water furnished under a standard unit head.

Q4: What is Depression Head?
A: Depression Head is the height of the bottom of a well above the datum.

Q5: What are the units used in this calculation?
A: Yield is in m³/s, Specific Capacity is dimensionless, Depression Head is in meters, and the resulting Area is in square meters.
