Detailed explanation-1: -The slope of the Western Ghats is steep and that is the reason that these rivers have a rapid flow. They don’t have to travel much distance to drain into the sea. As a result, they don’t carry much sediments required to form deltas.
Detailed explanation-2: -The Periyar, Bharathappuzha, Pamba, Netravati, Sharavathi, Kali, Mandovi and Zuari rivers flow westwards towards the Western Ghats, draining into the Arabian Sea, and are fast-moving, owing to the steeper gradient.
Detailed explanation-3: -Detailed Solution Narmada river does not form delta before it drains into Arabian Sea near Gulf of Cambey(Khambhat). It forms estuary before it meets Arabian Sea. Narmada is a west flowing river, it originates from Amarkantak in Anuppur district of Madhya Prasesh.
Detailed explanation-4: -The west-flowing rivers form estuaries instead of Delta because, -The Deccan plateau has an eastward sloping which makes it more elevated than that of the eastern coast. Hence, there is no ground available for the formation of Delta.
