1. What is Depth of Water 2 Calculation?

The Depth of Water 2 calculation determines the water depth in the second well by subtracting the drawdown from the total aquifer thickness. This is essential for understanding groundwater levels and well performance in hydrogeological studies.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( h2 \) — Depth of water in well 2 (m)
• \( H \) — Thickness of aquifer (m)
• \( s2 \) — Drawdown in well 2 (m)

Explanation: This formula calculates the remaining water depth in the second well after accounting for the drawdown caused by pumping or other factors.

3. Importance of Depth of Water Calculation

Details: Accurate calculation of water depth in wells is crucial for groundwater management, well design, pumping test analysis, and understanding aquifer characteristics and behavior.

4. Using the Calculator

Tips: Enter aquifer thickness in meters, drawdown in well 2 in meters. Both values must be valid positive numbers, with drawdown not exceeding aquifer thickness.

5. Frequently Asked Questions (FAQ)

Q1: What is drawdown in a well?
A: Drawdown is the difference between the static water level and the pumping water level in a well, representing the drop in water level due to pumping.

Q2: Why is aquifer thickness important?
A: Aquifer thickness determines the total water-bearing capacity and influences the well's yield and sustainable pumping rates.

Q3: Can drawdown exceed aquifer thickness?
A: No, drawdown cannot exceed the total aquifer thickness as this would mean the well has completely dewatered that portion of the aquifer.

Q4: How is this calculation used in practice?
A: This calculation is used in pumping test analysis, well design, groundwater modeling, and determining safe yield of wells and aquifers.

Q5: What factors affect drawdown in wells?
A: Drawdown is affected by pumping rate, aquifer properties (transmissivity, storativity), well construction, duration of pumping, and proximity to other pumping wells.
