Aquifer Thickness
Aquifer Thickness (at Midpoint between Equipotential lines) or otherwise is the thickness of aquifer in which the pore spaces of rock forming the aquifer may or may not be with water.
Symbol: b
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Discharge by Each Well when Two Well Interference
Discharge by Each Well when Two Well Interference is the sum of the individual well rates, adjusted for interference.
Symbol: Qt
Measurement: Volumetric Flow RateUnit: m³/s
Note: Value should be greater than 0.
Radius of Influence
The radius of influence is the distance from a pumping well to the point where the drawdown, or lowering of the water table, becomes negligible.
Symbol: R
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Radius of Well
The radius of well refers to the horizontal distance from the center of the well to its inner wall, essentially the well’s radius.
Symbol: r
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Distance Between Wells
Distance Between Wells refers to the center to center distance between the well.
Symbol: B
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Coefficient of Permeability
Coefficient of Permeability refers to the ease with which water can flow through the aquifer's pore spaces.
Symbol: K
Measurement: SpeedUnit: cm/s
Note: Value should be greater than 0.
Initial Piezometric Surface
The initial piezometric surface refers to the level at which groundwater naturally stands in a confined aquifer before any pumping or external influence.
Symbol: H
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Depth of Water
Depth of Water is the depth in the well measured above the impermeable layer.
Symbol: hw
Measurement: LengthUnit: m
Note: Value should be greater than 0.
