Indian Geography / Indian River System
South Indian Rivers
South Indian rivers are those rivers that are flowing in the Peninsular India. The major and important rivers of south India are
Mahanadi, Godavari, Cauvery, Krishna, Narmada and Tapti. All the major southern rivers of India drain into the Bay of Bengal except Narmada and
Tapti or Tapi, which are west flowing peninsular rivers.
South Indian rivers are seasonal or ephemeral rivers and their source is mainly Monsoons. Only Cauvery is regarded as perennial river
of south India because it receives rains from both North-East as well as South-West monsoons.
Generally, the Peninsular rivers of India are called consequent rivers because here the topography is formed first and channels are formed next.
These are old or mature rivers having meandering course. The inflows in these rivers is less and Damming is relatively easier on South Indian
