What is Discharge for Partially Penetrating Well?

The discharge for a 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. This discharge is affected by factors like the hydraulic conductivity of the aquifer, the length of the well screen, the drawdown, and the well's radius. In partially penetrating wells, flow towards the well is more complex due to the incomplete interaction with the entire aquifer thickness, leading to potential reductions in efficiency and increased head losses compared to fully penetrating wells.
