Inland Drainage Basin Rivers are those Indian rivers which journey towards the interior parts India. A drainage basin is the catchment area of the river or a land area which accumulates water from rain or snow melt and drains downhill into a river, lake, reservoir, sea or ocean. The drainage basin acts like a funnel, collecting all the water within the area covered by the basin and channeling it into a waterway. Inland drainage basin is formed by rivers pouring their waters in a lake or an inland sea. Indian water bodies comprise of rivers like Himalayan Rivers, Deccan Rivers and Coastal Rivers. Most of the rivers enter the Bay of Bengal, while some rivers enter the Arabian Sea. Inland Drainage Basin Rivers do not enter a sea or ocean. They are present in different parts of India. The rivers located in north and south India are given below.

Ghaggar River

Significance of Inland Drainage Basin in India
Inland Drainage Basin in India plays an important role in the hydrology of the country. It can become a logical unit for studying the movement of water within the hydrological cycle. Inland Drainage Basins are also considered to be important elements in ecology. When water flows over the ground and along the rivers it picks up nutrients, sediment and pollutants. These minerals get transported towards the outlet of the basin and affect the ecological processes. Moreover, these drainage basins are historically important too. They help in determining boundaries and enhance Indian trade through water.
