Detailed explanation-1: -A watershed is an area of land that drains rainfall and snowmelt into streams and rivers.

Detailed explanation-2: -A drainage basin is an area of land where water from rain or snow melt drains downhill into a body of water such as a river, lake, wetland or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surface from which water drains into those channels.

Detailed explanation-3: -The term “drainage area” is defined as the land area where precipitation falls off into creeks, streams, rivers, lakes, and reservoirs. It is a land feature that can be identified by tracing a line along the highest elevation between two areas on a map, often a ridge.

Detailed explanation-4: -he drainage basin hydrological cycle: the water balance. This is a series of processes by which water is evaporated from the sea and eventually condenses and precipitates over the land. It is the main input to the drainage basin and you can read detailed notes on this process at the Met Office’s website.

Detailed explanation-5: -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.
