West Flowing Rivers of Peninsular India Don't Form Delta
The reason these streams have a fast flow is that the western Ghats have a steep inclination. As a result, the streams discharge their waste into the distant ocean. The Narmada and Tapti stream both flows concurrently through the valleys with cracks, retaining the dissolved material they carry in the breaks of the problem areas. As a result, they do not form deltas.
Another reason why the streams on the western side don't create deltas is because of the tides. The Narmada and Tapti rivers both flow concurrently in the rift valleys. As a result, the eroded material they carry is deposited in the fault zone fissures.
