Foothill hydrology refers to the study of water resources in hilly or mountainous regions where water supply and distribution are often impacted by complex terrain and weather patterns. Effective management and allocation of water resources require accurate and timely information about their availability and distribution. Geospatial applications have emerged as powerful tools in water resources management, providing crucial insights into water systems’ spatial and temporal dynamics in foothill hydrology. It aims to bridge the gap between theoretical concepts and practical applications and emphasizes the acquisition of practical experience with software relevant to water resources engineering, enabling participants to make informed decisions and develop sustainable solutions. This review paper presents a comprehensive analysis of geospatial applications in the field of foothill hydrology, highlighting their contributions, advancements, and challenges. It also, explores various remote sensing platforms, such as a wide range of areas within water resources engineering, including watershed delineation, rainfall-runoff simulation, stormwater management, land use/land cover (LULC), satellite image processing, river profile study, and various water resource modeling. Furthermore, integrating remote sensing with geographic information systems (GIS) facilitates the development of accurate water resource databases, enabling efficient decision-making processes. This review work provides a comprehensive analysis of geospatial applications in foothill hydrology water management, highlighting their transformative potential in addressing the challenges of water scarcity, and sustainable water governance. The findings of this review would serve as a valuable resource for researchers, policymakers, and practitioners involved in water resources management and planning.
