Borehole drilling and groundwater layers: 1. Topsoil: The uppermost soil layer at ground level. 2. Subsoil: Denser soil beneath the topsoil, usually with less organic matter. 3. Unconfined aquifer: A water-bearing layer where groundwater is stored and can be accessed easily; its upper surface is the water table. 4. Impermeable layer: A layer (clay/rock) that does not allow water to pass through, separating aquifers. 5. Confined aquifer: A deeper water-bearing layer trapped between impermeable la

Identifying Groundwater Recharge and Discharge Zones Using GIS Layers One of the most important GIS layers in this process is topography, often represented using a Digital Elevation Model. Elevation controls the direction of surface water flow and strongly influences groundwater movement. Areas with higher elevation typically act as recharge zones, where water moves downward into the subsurface. Lower-lying areas, valleys, and depressions often serve as discharge zones, where groundwater emerges
