摘要

This research investigates the hydrogeological and geospatial factors that influence the potential of boreholes for groundwater extraction. Key parameters, including drawdown, pumping rate, transmissivity, hydraulic conductivity, and storativity, were evaluated to determine the most suitable borehole sites for sustainable groundwater abstraction. The study entailed gathering information on five boreholes (BH1 to BH5), which were measured in terms of drawdown, pumping rate, transmissivity, hydraulic conductivity, and Storativity. Slope, drainage density, and lineament density were also considered to assess their impact on groundwater availability. The findings revealed significant variations across boreholes: BH1 exhibited the highest drawdown (35.32 m) and pumping rate (2.06 m³/day), while BH2 demonstrated the highest transmissivity (26.11 m²/day), indicating efficient water flow. The geospatial analysis revealed moderate-sloping and high drainage density areas, which resulted in a better occurrence of groundwater recharge. Utilising hydrogeological and geospatial elements is a crucial part of successfully optimising borehole location, groundwater extraction, and sustainable water resource management. This combination has provided insight into local groundwater and is essential for sustainable water management.
