Which of the following rivers makes an estuary?
(a) Cauvery
(b) Krishna
(c) Narmada
(d) Ganga
Solution: (c)
Most of the west flowing rivers of Indian peninsula do not form delta. They form estuary. Narmada is one of them. It is so because rocky terrain of the Western Ghats does not allow the rivers to spread out much, and there is not sufficient plain stretch of land between the Arabian sea and Western Ghats for Narmada to slowdown and bifurcate into distributaries. Narmada forms an estuary of 21 km at the Gulf of Khambat. The river is presently partially navigable in the estuary reach around Bharuch but the river has never been a transport artery.
Which one of the following rivers of Peninsular India does not join Arabian Sea?
