1. What Is The Depth Of Water In Well 1 Given Drawdown In Well 1 Formula?

The Depth Of Water In Well 1 Given Drawdown In Well 1 formula calculates the water depth in the first well by subtracting the drawdown from the total aquifer thickness. This provides insight into the remaining water column after pumping-induced decline.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( h1 \) — Depth of water in well 1 (m)
• \( H \) — Thickness of aquifer (m)
• \( s1 \) — Drawdown in well 1 (m)

Explanation: This straightforward calculation determines the actual water depth by accounting for the reduction caused by pumping activities.

3. Importance Of Depth Of Water Calculation

Details: Accurate water depth calculation is essential for groundwater management, well performance assessment, and determining sustainable extraction rates to prevent aquifer depletion.

4. Using The Calculator

Tips: Enter aquifer thickness and drawdown values in meters. Ensure drawdown does not exceed aquifer thickness for valid results.

5. Frequently Asked Questions (FAQ)

Q1: What is drawdown in well hydrology?
A: Drawdown is the reduction in hydraulic head observed at a well due to pumping, representing the drop in water level from static conditions.

Q2: Why is aquifer thickness important in this calculation?
A: Aquifer thickness defines the maximum available water column, serving as the baseline from which drawdown is subtracted to find current water depth.

Q3: Can drawdown exceed aquifer thickness?
A: No, drawdown cannot exceed aquifer thickness as it represents water level decline within the available saturated zone.

Q4: How does this calculation help in well design?
A: It helps determine appropriate well screen placement and pump setting depth to ensure continuous water availability during pumping.

Q5: What factors affect drawdown magnitude?
A: Pumping rate, aquifer properties, duration of pumping, and well construction characteristics all influence drawdown magnitude.
