Watersheds refer to the areas or regions where surface water flows and collects. Synonyms for the word watersheds include catchment, drainage basin, river basin, or hydrological basin. These terms often refer to the geographical boundaries of an area where water flows to a common body of water, such as an ocean, lake, or another river. These terms play an important role in understanding the natural water cycle and how water moves through the environment. Identifying a watershed can provide a better understanding of the impacts of human activities, climate change, or natural phenomena on the quality and availability of water resources in a particular region.
