The Narmada river creates the conventional border between South India and North India. The river runs to the west for a span of 1,312 km and flowed through the Gulf of Khambat (Cambay) into the Arabian Sea, in Gujarat. Like the Mahi River and the Tapti River, the Narmada River is a river flowing from east to west.
