India is a geographical paradise with a multitude of rivers flowing across the country. While most of the rivers in the country are east flowing in nature, i.e. they join the Bay Of Bengal, there are a few rivers that defy the odds and are west flowing, These west-flowing rivers ultimately end up in the Arabian Sea.

West Flowing Rivers of Peninsular India

  • The west-flowing rivers of Peninsular India are fewer and smaller as compared to their east-flowing counterparts.
  • The two major west-flowing rivers are the Narmada and the Tapi.
  • Other rivers: Shetrunji River, Bhadra, Dhandhar, Sabarmati, Mahi, Vaitarana, Kalinadi, Bedti river, Sharvati, Mandovi, Juari, Bharatpuzha, Periyar, Pamba river, etc.
  • This exceptional behavior is because these rivers didn’t form valleys and instead they flow through faults (linear rift, rift valley, trough) created due to the bending of the northern peninsula during the formation process of the Himalayas.
  • These faults run parallel to the Vindhyas and the Satpuras.
  • The Sabarmati, Mahi, and Luni are other rivers of Peninsular India which flow westwards.
  • Hundreds of small streams originating in the Western Ghats flow swiftly westwards and join the Arabian Sea.
  • It is interesting to note that the Peninsular rivers which fall into the Arabian Sea do not form deltas, but only estuaries.
  • This is due to the fact that the west-flowing rivers, especially the Narmada and the Tapi flow through hard rocks and hence do not carry any good amount of silt.
  • Moreover, the tributaries of these rivers are very small and hence they don’t contribute any silt.
  • Hence these rivers are not able to form distributaries or a delta before they enter the sea.
  • A few rivers in Rajasthan do not drain into the sea. They drain into salt lakes and get lost in the sand with no outlet to the sea. Besides these, there are the Desert Rivers which flow for some distance and are lost in the desert. These are Luni and others such as, Machhu, Rupen, Saraswati, Banas, and Ghaggar.
West flowing Rivers in India
  • An estuary is a partially enclosed body of water along the coast where freshwater from rivers and streams meets and mixes with saltwater from the ocean. (Primary productivity in estuaries is very high. Fishing is a dominant occupation around estuaries. Most of the estuaries are good bird sanctuaries).
  • Estuaries and the lands surrounding them are places of transition from land to sea and freshwater to saltwater.
  • Although influenced by the tides, they are protected from the full force of ocean waves, winds, and storms by such landforms as barrier islands or peninsulas.
  • Estuarine environments are among the most productive on earth, creating more organic matter each year than comparably-sized areas of forest, grassland, or agricultural land.
  • The tidal, sheltered waters of estuaries also support unique communities of plants and animals especially adapted for life at the margin of the sea.
  • Estuaries have important commercial value and their resources provide economic benefits for tourism, fisheries, and recreational activities.
  • The protected coastal waters of estuaries also support important public infrastructure, serving as harbors and ports vital for shipping and transportation.
  • Estuaries also perform other valuable services. Water draining from uplands carries sediments, nutrients, and other pollutants to estuaries. As the water flows through wetlands such as swamps and salt marshes, much of the sediments and pollutants are filtered out.
  • Saltmarsh grasses and other estuarine plants also help prevent erosion and stabilize shorelines Mangroves.

Narmada River

  • Narmada is the largest west flowing river of peninsular India.
  • Narmada flows westwards through a rift valley between the Vindhyan Range on the north and the Satpura Range on the south.

  • Its total length from its source in Amarkantak to its estuary in the Gulf of Khambhat is 1,310 km.
  • The hilly regions are in the upper part of the basin, and lower-middle reaches are broad and fertile areas well suited for cultivation.
  • Jabalpur is the only important urban center in the basin.
  • The river slopes down near Jabalpur where it cascades (a small waterfall, especially one in a series) 15 m into a gorge to form the Dhuan Dhar (Cloud of Mist) Falls.
  • Since the gorge is composed of marble, it is popularly known as the Marble Rocks.
  • It makes two waterfalls of 12 m each at Mandhar and Dardi. Near Maheshwar, the river again descends from another small fall of 8 m, known as the Sahasradhara Falls.
  • There are several islands in the estuary of the Narmada of which Aliabet is the largest.
  • The Narmada is navigable up to 112 km from its mouth.

Mahi River

Tributaries of Mahi:

  • Som
    • This is the right bank tributary of Mahi. Som river rises near Som on the Eastern slopes of the Aravalli hills in the Udaipur district of Rajasthan at an elevation of 600 m above m.s.l. and flows in the Eastern direction to join the main river Mahi on the right bank 6.3 km upstream of Paderdibadi site in Dungarpur district of Rajasthan. Its total length is about 155 km. The total drainage area of Som is 8707 sq. km. Gomti & Jakham are the major right bank sub tributaries of Som.
  • Anas
    • This is a Left bank tributary of Mahi. Anas River rises near Kalmora on the Northern slopes of Vindhyas in Jhabua district in Madhya Pradesh at an elevation of 450 m above m.s.l. and flows in the North – West direction and joins the main river Mahi on the left bank in the Dungarpur district in Rajasthan. It has a total length of about 156 km and a total drainage area of 5604 sq. km.
  • Panam
    • This is a Left bank tributary of Mahi. Panam river rises near Bhadra on the Northern slopes of the Vindhyas near the Jhabua district in Madhya Pradesh at an elevation of about 300 m above m.s.l. and flows in the North – West direction and joins the main river on the left bank in the Panchmahal district of Gujarat. It has a total length of about 127 km and a drainage area of about 2470 sq. km.

Luni River

  • The Luni or the Salt River (Lonari or Lavanavari in Sanskrit) is named so because its water is brackish below Balotra.
  • Luni is the only river basin of any significance in Western Rajasthan, which forms the bulk of the arid zone.
  • Luni originates from the western slopes of the Aravalli ranges at an elevation of 772 m near Ajmer flowing in the southwest direction and traversing a course of 511 km in Rajasthan, it finally flows into the Rann of Kachchh (it gets lost in the marsh).
  • Most of its tributaries drain the steep northwest of Aravalli hills and join it on the left side. Its total catchment area falls in Rajasthan.
  • The peculiarity of this river is that it tends to increase its width rather than deepening the bed because the banks are of soils, which are easily erodible whereas beds are of sand. The floods develop and disappear so rapidly that they have no time to scour the bed.
Luni River

West flowing Rivers of the Sahyadris (Western Ghats)

  • About six hundred small streams originate from the Western Ghats and flow westwards to fall into the Arabian Sea.
  • The western slopes of the Western Ghats receive heavy rainfall from the south-west monsoons and are able to feed such a large number of streams.
  • Although only about 3% of the areal extent flow swiftly down the steep slope and some of them make waterfalls.
  • The Jog or Gersoppa Falls(289 m) made by the Sharavati river is the most famous waterfall of India.
    • Sharavati is a river which originates and flows entirely within the state of Karnataka.

Ghaggar River – Inland Drainage

  • Some rivers of India are not able to reach the sea and constitute inland drainage.
  • Large parts of the Rajasthan desert and parts of Aksai Chin in Ladakh have inland drainage.
  • The Ghaggar is the most important river of inland drainage. It is a seasonal stream that rises on the lower slopes of the Himalayas and forms the boundary between Haryana and Punjab.
  • It gets lost in the dry sands of Rajasthan near Hanumangarh after traversing a distance of 465 km.
  • Earlier, this river was an affluent of the Indus, the dry bed of the old channel is still traceable.
  • Its main tributaries are the Tangri, the Markanda, the Saraswati and the Chaitanya.
  • It contains a lot more water in the rainy season when its bed becomes 10 km wide at places.
  • Most of the streams draining western slopes of the Aravalli Range dry up immediately after they enter the sandy arid areas to the west of this range.

Mhadei river

  • Mahadayi or Mhadei, the west-flowing river, originates in Bhimgad Wildlife Sanctuary (Western Ghats), Belagavi district of Karnataka.
  • It is essentially a rain-fed river also called Mandovi in Goa.
  • It is joined by a number of streams to form the Mandovi which is one of two major rivers (the other one is the Zuari river) that flows through Goa.
  • The river travels 35 km in Karnataka; 82 km in Goa before joining the Arabian Sea.
  • Kalasa-Banduri Nala project
    • Undertaken by the Government of Karnataka to improve drinking water supply to the Districts of Belagavi, Dharwad, and Gadag. It involves building across Kalasa and Banduri, two tributaries of the Mahadayi river to divert 7.56 TMC of water to the Malaprabha river.
    • Kalasa-Banduri project was planned in 1989Goa raised an objection to it.

Usability of Rivers

  • Source of fresh water, irrigation, hydro-electric production, navigation, etc.
  • The Himalayas, Vindhyas, Satpuras, Aravalis, Maikala, Chhotanagpur plateau, Meghalaya plateau, Purvachal, Western and the Eastern Ghats offer possibilities of large scale water power development.
  • Sixty percent of the total river flow is concentrated in the Himalayan rivers, 16 percent in the Central Indian rivers (the Narmada, the Tapi, the Mahanadi, etc.), and the rest in the rivers of the Deccan plateau.
  • The Ganga and the Brahmaputra in the north and northeastern part of the country, the Mahanadi in Odisha, the Godavari and the Krishna in Andhra and Telangana the Narmada and the Tapi in Gujarat, and the lakes and tidal creeks in coastal states possess some of the important and useful waterways of the country.
  • In the past, they were of great importance, which suffered a great deal with the advent of rail and roads.
  • Withdrawal of large quantities of water for irrigation resulted in the dwindling flow of many rivers.
  • The most important navigable rivers are the Ganga, the Brahmaputra, and the Mahanadi. The Godavari, the Krishna, the Narmada, and the Tapi are navigable near their mouths only.
