Groundwater is a primary water source in Bharatpur municipality, which contributes to water supply for various purposes including drinking, irrigation, sanitary, and industrial. Bharatpur has become an attractive place to live due to the availability of educational, medical, and employment amenities. These facilities are contributing to the rapid growth of population and infrastructure expansion over the municipality. Consequently, the rapidly increasing population leads to the need for more groundwater withdrawal to fulfill the water demand, decreasing the recharge area due to concrete cover and increasing the flooding problem during the monsoon season. As a result, these consequences are altering the ecosystem of groundwater and affecting the sustainability of the water supply system in the municipality. Despite the risk of lacking water supply problems in the municipality, there has been little scientific research on sustainable groundwater management. In response, this study seeks to categorize and delineate potential groundwater recharge zones using remote sensing and geographical information system approaches. By employing these advanced methodologies, the study expects to deliver practical insights for long-term groundwater management practices. The analytical hierarchy process (AHP) is a widely accepted multi-criteria decision analysis (MCDA) method for groundwater assessment and other scientific investigations. In this paper, the author analyzes key influencing factors for groundwater recharge and utilizes GIS software to create thematic layers of maps for each factor. These factors include physiography, parent soil, land use and land cover, drainage density, lineament density, slope, and proportion of clay. By integrating these thematic layers of maps using the AHP and WOA methodologies, the study aims to identify possible groundwater recharge zones in the Bharatpur municipality, Chitwan, Nepal. The findings reveal that a significant portion of the region has a moderate to high potential for groundwater recharge in the southern part and the northern part was found to be a low potential for groundwater recharge. Additionally, the derived potential groundwater recharge map has the potential to offer invaluable support to urban planners and policymakers. Identifying places suitable for groundwater recharge allows for more informed decision-making to protect groundwater resources and the surrounding ecosystem. This proactive approach is consistent with the larger goal of achieving sustainable development in the study region, which promotes an equilibrium between urbanization and environmental conservation.
