Geography A'Level _ Hydrology _ The Drainage Basin

Hydrology is the scientific study of the movement, distribution, and management of water on Earth. It encompasses the water cycle, including precipitation, evaporation, and runoff, and examines how water interacts with the environment.

Drainage Basin: Also known as a watershed or catchment area, a drainage basin is a region where all precipitation collects and drains into a common outlet, such as a river, lake, or ocean. It is a critical concept in hydrology, as it defines the area of land that contributes to the flow of a particular water body.

Components: A drainage basin includes various elements such as rivers, streams, tributaries, and their surrounding land. It is influenced by factors like topography, land use, and climate, which affect how water flows through the basin.

Importance: Understanding drainage basins helps in managing water resources, predicting flood events, and implementing effective land use practices. It also aids in the protection of water quality and the preservation of ecosystems within the basin.
