Baitarni
Explanation
The drainage system of Peninsular India is divided into two major groups based on the direction of flow: rivers flowing into the Arabian Sea (west-flowing) and rivers flowing into the Bay of Bengal (east-flowing). The direction of flow is primarily determined by the water divide formed by the Western Ghats, the Aravallis, and the Vindhyas.
