Water sources research focuses on studying and managing the various natural sources of water available to communities, including surface water bodies such as rivers, lakes, and reservoirs, as well as groundwater aquifers. Researchers in this area investigate the quality, quantity, and sustainability of water sources, as well as potential impacts from human activities and environmental factors. This research is crucial for ensuring access to safe and reliable water supplies for drinking, agriculture, industry, and other purposes. Methods used in water sources research often include hydrological modeling, water quality testing, and analysis of water use patterns.
