GEOLOGY

Detailed explanation-1: -A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers. These smaller bodies of water flow into larger ones, including lakes, bays, and oceans.

Detailed explanation-2: -A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel.

Detailed explanation-3: -drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams.

Detailed explanation-4: -For example, the watershed of a lake would include not only the streams entering that lake but also the land area that drains into those streams and eventually the lake. Drainage basins generally refer to large watersheds that encompass the watersheds of many smaller rivers and streams.

Detailed explanation-5: -Precipitation-the ultimate source of water to the watershed. Continuous Ridgeline-determines the boundary line between adjacent watersheds.
