Abstract

As urban expansion and unpredictable rainfall have intensified groundwater stress in Indian urban cities, as seen in Gandhinagar, Gujarat this study creates an entropy-weighted GIS framework integrating DRASTIC and GALDIT models to assess groundwater vulnerability assessment. The seven hydrogeological parameters such as, depth to water table, net recharge, aquifer and soil media, topography, impact of vadose zone, and hydraulic conductivity were standardized in GIS-based environment and weighted using entropy approach, with values ranging from 0.08 to 0.21 depending on spatial variability. The resulting groundwater vulnerability index classified Gandhinagar into five zones: very low [12%], low [24%], moderate [31%], high [21%], and very high [12%]. The validation was performed through comparison with groundwater quality records, showing consistency with nitrate [NO-3] and salinity hotspots validated against hydrochemical records. The GIS-based framework demonstrates that entropy weighting improves objectivity by reducing subjective bias in parameter selection. The results provide planners with a reproducible tool to integrate groundwater sensitivity into climate-resilient urban infrastructure planning.
