Drainage Basin - GCSE Geography Definition

A drainage basin, also known as a river basin or catchment area, is an area of land where precipitation collects and drains into a river. It is defined by the topography of the surrounding landscape, with ridges or hills forming the boundaries, known as watersheds. All the water within a drainage basin converges into a single stream or river system. Understanding drainage basins is essential in GCSE Geography, as they play a critical role in the hydrological cycle and influence patterns of water flow, flood risks, and ecosystem dynamics. These areas are fundamental to managing water resources and assessing environmental impacts.
