The Narmada, also called the Rewa, is a river in central India and the fifth longest river in the Indian subcontinent. It is the third longest river that flows entirely within India, after the Godavari and the Krishna.

The west flowing rivers do not make delta, but estuaries. Many west flowing rivers like Narmada passes through rift vallies.This river contains very few amounts of Slits and due to its fast speed it cannot make delta. ... When these fast flowing rivers reach to its mouth it become unable to deposit its slits, due to this reason slits falls in to the sea.

Explanation:

The Narmada River does not form a delta.

Reason:

A delta is a landform that forms at the mouth of a river where it enters another body of water, such as a lake, sea, or ocean. Deltas are typically characterized by sediment deposition and the formation of distributaries.

Characteristics of a Delta:
- Sediment Deposition: Deltas are formed when a river carries sediment (such as sand, silt, and clay) downstream and deposits it at the river's mouth. This sediment builds up over time and forms the delta.
- Distributaries: Deltas often have distributaries, which are smaller channels that branch off from the main river and carry water and sediment to different areas of the delta.
- Fan-shaped Formation: Deltas typically have a fan-shaped or triangular formation, with the river's main channel splitting into multiple smaller channels as it reaches the delta.

Analysis of the Given Rivers:
a) Godavari: The Godavari River forms a delta. It is the second longest river in India and its delta is located in the state of Andhra Pradesh.
b) Mahanadi: The Mahanadi River also forms a delta. It is a major river in East-Central India and its delta is located in the state of Odisha.
c) Narmada: The Narmada River does not form a delta. The Narmada River is one of the major rivers in Central India, but it does not have a delta. Instead, it forms a gorge known as the Marble Rocks in Jabalpur, Madhya Pradesh.
d) Krishna: The Krishna River forms a delta. It is one of the longest rivers in India and its delta is located in the state of Andhra Pradesh.

Therefore, among the given options, the Narmada River is the one that does not form a delta. It is important to note that the absence of a delta does not make a river any less significant or influential in its region.
