Remote Sensing in Hydrogeology The Advanced Center for Water Resources Development and Management focuses on understanding water sources such as rain, snow, and glaciers, which melt to form streams. Historically, aerial photography tracked glacier movement, but now satellite imagery is utilized for monitoring. Techniques for measuring snow thickness have evolved from field methods to GPS technology. The interaction of rainwater and meltwater with the ground leads to surface runoff and groundwater recharge, influenced by soil permeability. Additionally, remote sensing helps identify springs, fracture zones, and groundwater features, while thermal and microwave imagery reveal temperature variations and buried structures.
