Note: Value can be positive or negative.
Discharge for Partially Penetrating Well
Discharge for Partially Penetrating Well refers to the volume of water extracted from an aquifer when the well does not extend through the entire thickness of the aquifer.
Symbol: Qv
Measurement: Volumetric Flow RateUnit: m³/s
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
