The thickness of aquifer from impermeable layer given drawdown in well 2 refers to the total vertical extent of the aquifer measured from the impermeable base to the initial water table level. This parameter is crucial in hydrogeology for understanding aquifer characteristics and groundwater flow.
The calculator uses the formula:
Where:
Explanation: This formula calculates the total aquifer thickness by adding the water depth measurement and the drawdown observed in the second monitoring well.
Details: Accurate determination of aquifer thickness is essential for groundwater resource assessment, well design, contaminant transport modeling, and sustainable water management practices.
Tips: Enter the depth of water in well 2 and the drawdown measurement in well 2. Both values must be positive numbers measured in meters.
Q1: What is aquifer thickness?
A: Aquifer thickness is the vertical distance from the impermeable base layer to the initial water table level of an aquifer.
Q2: Why is drawdown measurement important?
A: Drawdown measurements help determine how much the water level has dropped due to pumping, which is essential for calculating aquifer properties.
Q3: How accurate is this calculation method?
A: This method provides a direct measurement approach but may require corrections in complex geological settings or anisotropic aquifers.
Q4: When should this calculation be used?
A: This calculation is particularly useful in pumping test analysis and groundwater investigation studies where multiple monitoring wells are available.
Q5: Are there limitations to this approach?
A: This method assumes homogeneous aquifer conditions and may not account for variations in aquifer properties or complex geological structures.
