Which of the following rivers does not form a delta?
Conditions for delta formation by a river:
- The river must have gentle gradient in its lower course
- The river must carry large amount of sediments along it
- The coastal plains or area where mouth of river lies should be wide
Though Narmada originates far from Western Ghats and empties into the Arabian Sea, the river flows through a rift valley at a steep gradient which increases its speed. Also, the west coastal plains are less wider than that required for delta formation by Narmada.
