A catchment area, also known as a drainage basin or watershed, is an area of land from which water drains into a specific river, lake, or other body of water. It is defined by the topography of the land, where all precipitation falling within the catchment area eventually flows into the same water body. The boundaries of a catchment area are typically determined by the highest elevations or ridges of the surrounding landscape, with the area inside these boundaries being influenced by the water flow patterns towards a common outlet. Catchment areas are important for water management, as they help to study and understand the movement and quality of water within a specific region.
