What is the difference between watershed and drainage basin?

Drainage basin: A drainage basin is an extent of land where water from rain or snow melt drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. Watershed: In the technical sense, a watershed refers to a divide that separates one drainage area from another drainage area.

What is a coastal watershed?
