A catchment area is a region where all the water that falls as rain or snow drains into a specific body of water, such as a river, lake, or reservoir. This area is important for managing water resources, as it helps determine how much water is available for drinking, agriculture, and other uses. In addition to water management, catchment areas are also significant for environmental studies. They can influence local ecosystems and biodiversity, as the land and water within the catchment area support various plants and animals. Understanding catchment areas helps in planning for sustainable development and conservation efforts.
