They form longer courses with broader valleys, larger drainage basins, and create deltas near their mouths. Conversely, west-flowing rivers such as the Narmada and Tapi (Tapti) originate in the Western Ghats, flow towards the Arabian Sea with shorter courses, cut through rift valleys, and have smaller drainage basins with limited agricultural impact.
