Most of the Western flowing rivers travel a lesser distance than eastern flowing rivers before getting into the sea. On way to the West coast through hard rocks and over a higher gradient, they couldn’t collect a large amount of Slit and flow with very high speed compared to East flowing rivers. Eastern rivers flow through broken hills and mountain ranges.

So, they are widened and flow with lesser velocity before entering into sea. So, they deposit sediments and silt before entering into the sea and can form a Delta.
