Explanation:

The Narmada River, also called the Rewa and previously also known as Nerbudda, is a river in central India after the Godavari, and the Krishna. It is also known as "Life Line of Madhya Pradesh and Gujarat" for its huge contribution to the state of Madhya pradesh and Gujarat in many ways. Narmada rises from Amarkantak Plateau near Anuppur district Madhya Pradesh. It forms the traditional boundary between North India and South India and flows westwards over a length of 1,312 km (815.2 mi) before draining through the Gulf of Khambhat into the Arabian Sea, 30 km (18.6 mi) west of Bharuch city of Gujarat. 

 It is one of the rivers in India that flows in a rift valley, flowing west between the Satpura and Vindhya ranges.
