What are the properties of a watershed?

A watershed, or drainage basin, is characterized by its topography, hydrology, and land use. It is an area of land where all precipitation collects and drains into a common outlet, such as a river or lake. Watersheds are defined by their boundaries, known as ridgelines, which separate one watershed from another. Additionally, they play a crucial role in managing water quality, controlling flooding, and supporting diverse ecosystems.
