GIS and Remote Sensing-Based Multi-Criteria Analysis for Delineation of Groundwater Potential Zones: A Case Study for Industrial Zones in Bangladesh

Groundwater is a crucial natural resource that varies in quality and quantity across Bangladesh. Increased population urbanization place enormous demands on groundwater supplies, reducing both their quantity. This research aimed to delineate the potential zone Gazipur district, Bangladesh, by integrating eleven thematic layers. Data information were gathered from Landsat 8, digital elevation model, google earth engine, several ancillary sources. A multi-criterion decision-making (MCDM) based analytical hierarchy process (AHP) was used GIS platform estimate index. The index values finally classified into five sub-groups: very low, moderate, high, high generate water (GWPZ) map. results show about 0.002% (0.026 km2) of area 3.83% (63.18 56.2% (927.05 medium, 39.25% (647.46 rest 0.72% (11.82 high. validation GWPZ maps level data at 20 observation wells showed an overall accuracy 80%. In addition, ROC curve 84% when validated with inventory points study region. Overall, this presents easy practical approach for identifying zones, which may help improve planning sustainable management.
