| Abstract | The essentiality of water extends beyond sustaining life to assisting agricultural, domestic, and industrial needs. Climate variability, population growth, and land use transitions have intensified pressure on groundwater resources. The fall in water levels and disappearance of weathered zones in semi-arid regions such as the Choutuppal watershed, Telangana, India are an outcome of persistent droughts and exhaustive groundwater exploitation. In spite of the need, integrated spatial analysis identifying areas vulnerable to groundwater depletion, flooding, and drought are limited. This study seeks to map groundwater potential zones along with flood and drought vulnerability using geospatial techniques. Remote sensing and GIS-based technologies were employed in this study. The data was combined with information on drainage density, precipitation, slope, elevation, soil type, and land use or landcover layers and weighted overlay analysis was carried out to map groundwater potential zones. This was followed by an analysis utilizing SCS-CN method for flood risk and standardized precipitation Index (SPI) analysis of 72 years of rainfall data to evaluate drought variations highlighting the importance of mapping flood and drought patterns. Results indicate groundwater potential zones as very poor (0.0045 km�), poor (13.75 km�), moderate (52.99 km�), good (26.90 km�), and very high (0.07 km�). Flood risk zones were categorized as very low (0.99 km�), low (17.79 km�), moderate (48.95 km�), high (25.87 km�), and very high (0.11 km�). Drought-prone zones were mapped as very low (4.07 km�), low (33.66 km�), moderate (56.23 km�), and high (4.38 km�). Consolidating these results offers implementable strategies and insights for sustainable groundwater management, flood mitigation, and drought preparedness, strengthening informed decision-making for regional water resource planning. |
