What is a river basin?

Answer: A river Basin is defined as the part of the land area drained over by a river and the following river tributaries.

    There are certain characteristic features of the River Basin, such as the watershed where the water is at a higher ground and always flows downhill down the slope. The water source, the starting point of a river, is also a characteristic feature of the river basin. The tributaries which drain the land area always flow into a larger river. Generally, many watersheds comprise a river Basin.
