The incorporation of Remote Sensing (RS) and Geographic Information System (GIS) technologies for the precise assessment of groundwater potential in the Himalayan region represents a significant leap in water resource management. This study aims to provide significant insights into the evolving field of hydrology through a review by bridging the gap between old methods and contemporary technology, offering a model for areas with comparable water resource complexity. The methodology used in the study comprises the amalgamation of RS and GIS technologies to evaluate groundwater potential in the Himalayan region. These technologies are used to gather and process data on variables like temperature, soil moisture, and land use/ land cover dynamics. This paper identifies some of the existing issues that need to be addressed by the integration of modern RS and GIS technologies. The key findings include the identification of the difficulties such as topography, geological heterogeneity, rainfall that is unpredictable due to climate change, and human factors like urbanization, deforestation, and changing land use that affect groundwater supplies. The study contributes both scientifically and practically to sustainable water resources management. Through this study, we not only deciphered the current state of water resources but also forged a path toward sustainable and data-driven water resource managing practices in one of the world’s most critical and challenging ecosystems.
