The major west-flowing rivers in peninsular India are the Narmada and Tapi, which flow into the Arabian Sea. Other significant west-flowing rivers include the Mahi, Sabarmati, Luni (inland drainage), Periyar, Bharatpuzha, etc. Comparing the basin sizes of the rivers listed in the options:
– Narmada River Basin: Approximately 98,796 sq km. It is the largest west-flowing river basin in Peninsular India.
– Tapi River Basin: Approximately 65,145 sq km.
– Mahi River Basin: Approximately 34,842 sq km.
– Sabarmati River Basin: Approximately 21,674 sq km.
Arranging these in decreasing order of basin size: Narmada (98,796) > Tapi (65,145) > Mahi (34,842) > Sabarmati (21,674).
The correct order is Narmada — Tapi — Mahi — Sabarmati.
Narmada and Tapi are the largest west-flowing rivers of Peninsular India, flowing through rift valleys. Basin size refers to the total area drained by a river and its tributaries.
Most major peninsular rivers in India flow eastwards into the Bay of Bengal, forming large deltas (e.g., Ganga-Brahmaputra, Mahanadi, Godavari, Krishna, Cauvery). The west-flowing rivers, particularly Narmada and Tapi, flow through rift valleys and form estuaries instead of deltas.
