Q. Which of the following rivers does not form a delta?
Answer: Narmada
Notes: Narmada River is the largest river in India that does not form a delta. The Narmada River flows west and drains into the Arabian Sea. The Narmada River and the Tapi River are the only rivers in peninsular India that do not form deltas. The Tapi River also does not form a delta because it has a steep gradient and a swift current. The Tapi River carries the sediments it erodes from its source to the mouth without depositing them. Most rivers flowing west from the Western Ghats do not form deltas because they don't have to travel much distance to drain into the sea. As a result, they don't carry much sediments because they don't have the time to.
