Groundwater Infiltration Trends in the Major Basin of Ahmedabad District, Gujarat, India

Rapid urbanization and land-use change resulted in a major reduction of groundwater recharge regions. Infiltration through porous terrain is the cause of groundwater recharge. Due to industrialization, urbanization, and population growth, groundwater extraction in the Ahmedabad district's Sabarmati Sub-basin has increased in recent decades. In order to create sustainable groundwater management plans, researchers and local authorities now need to evaluate the water resources in the Ahmedabad district. The spatiotemporal trends of groundwater infiltration upstream of the Vasna Barrage on the Sabarmati River from 1980 to 2020 are investigated in this study. The non-parametric Mann- Kendall test was used to analyze the premonsoon groundwater infiltration trend. Results indicate a statistically significant downward trend in pre-monsoon infiltration.
