A drainage basin is an area of land where all the water that falls as rain or snow drains into a common outlet, such as a river, lake, or ocean. This area collects water from various sources, including streams, rivers, and rainfall, and channels it towards the outlet. The boundaries of a drainage basin are defined by high points, like hills or mountains, which separate it from neighboring basins.
Understanding drainage basins is important for managing water resources and preventing flooding. For example, when heavy rain occurs, the water flows through the basin and can affect nearby communities. Proper management helps protect ecosystems and ensures clean water for people and wildlife, making it a vital aspect of environmental science and conservation.
