Abstract
The application of the Normalized Difference Water Index (NDWI) in the assessment of water resources is a pivotal tool for understanding spatiotemporal variations in water bodies. In this study, NDWI analysis was conducted for Gadag Taluk across the years 2019, 2020, and 2021. The analysis revealed significant insights into water presence and distribution trends within the region.The NDWI values calculated for each year indicated the existence of water bodies of varying magnitudes. The highest NDWI values ranged from -0.0975 to -0.0825, representing areas with a higher concentration of water, while the lowest NDWI values ranged from -0.455 to -0.465, suggesting regions with reduced water content or potential land cover changes. Consistency in NDWI patterns across the three years indicated a stable spatial distribution of water bodies within Gadag Taluk. While minor variations were observed between years, the overall trend underscores the enduring presence of water resources. These findings have significant implications for water resource management, disaster preparedness, and sustainable development. The study's outcomes emphasize the need for informed decision-making to safeguard water resources and support various socio-economic activities. Future research could explore the underlying factors influencing NDWI variations and integrate NDWI analysis with complementary datasets for a comprehensive understanding of water dynamics
