What is the difference between a watershed catchment and drainage basin river basin )?
Watershed: In the technical sense, a watershed refers to a divide that separates one drainage area from another drainage area. Drainage basins drain into other drainage basins in a hierarchical pattern, with smaller sub-drainage basins combining into larger drainage basins.
Is catchment and watershed the same?
A water catchment (commonly referred to as a “watershed”) is an area of land where all water flows to a single stream, river, lake or even ocean. HCA encourages the use of the term “water catchment” over “watershed.” A water catchment area is home to a complete water-cycle system.
What is meant by watershed area or catchment area?
1) An area from which surface runoff is carried away by a single drainage system. 2) The area of land bounded by watersheds draining into a river, basin or reservoir.
What is the difference between a basin and river?

How do you define catchment area?

What is the difference between catchment area and watershed?
A river drains the water collected from a specific area, which is called its catchment area. 2.Watershed. The land area that drains runoff( rain or snow) into a lake, river , or a stream is called watershed.
What is the difference between a watershed and a river basin?
Usually smaller catchment areas are referred as “Watersheds” and larger catchment areas are referred as “River Basins”. Actually your argue all very well, but it should be discussed together to your statement that smaller catchment is watershed and larger catchment is river basin is unusually, watershed is generally as an hydrological unity.
What is the definition of watershed?
The water that comes from different sources, such as rivers, ponds, creeks, rainfall, or melting snow and ice flows through them and into the water basin and out into another body of water, usually a larger one. These landforms are called watersheds which are the divides or elevations that separate the river basin or catchment area.
What is a drainage basin?
Drainage basin- The area drained by a river and its tributaries. Its borders are well defined by water divides that separate it from the other drainage basins. All the surface water in this particular area flows into a river though rills, gullies, rivulets, tributaries into the master stream and drains into the sea/lake.
