The peninsular rivers fall into two categories, viz., the coastal rivers and the inland rivers. The former are comparatively small streams. The west-coast rivers are of great importance. Although only 3 percent of the areal extent of the basins of India is drained by these rivers, as much as 14 percent of the country’s water resources are contained by them.
- Rivers rising from the Western Ghats: the Godavari, the Krishna, the Cauvery, the Pennar, the Palar, the Vaigai etc.
- Rivers flowing into the Arabian Sea: The Narmada, the Tapi, the Sharavati etc.
- Rivers originating in the Vindhyas and Satpura but flowing north-east towards Ganga: The Chambal, the Betwa, the Damodar, the Son, the Ken etc. The Narmada and the Tapi flow in the fault created by them during the Himalayan uplift.
