WEST FLOWING RIVERS OF PENINSULAR INDIA (Narmada – Tapi – Mahi)
WEST FLOWING RIVERS OF PENINSULAR INDIA
(Narmada – Tapi – Mahi)
West-flowing rivers are structurally controlled rivers of the Peninsular Plateau that drain into the Arabian Sea / Gulf of Khambhat. Unlike east-flowing rivers, they are shorter but economically and strategically significant.
1. NARMADA RIVER
(Largest West-Flowing Peninsular River | 5th Longest in India – 1,312 km)
The Narmada River originates from the Amarkantak Plateau (Madhya Pradesh) and flows westward through a rift valley between the Vindhya Range (north) and Satpura Range (south) before draining into the Arabian Sea. It is known as the “Lifeline of Madhya Pradesh and Gujarat.”
It has 41 primary tributaries —
- 22 Left Bank (from Satpura Range)
- 19 Right Bank (from Vindhya Range)
Major Tributaries
| Left Bank (Satpura Origin) | Right Bank (Vindhya Origin) |
| Tawa (Largest) | Hiran |
| Burhner | Barna |
| Banjar | Kolar |
| Sher | Man |
| Shakkar | Uri |
| Dudhi | Hatni |
| Ganjal | Orsang |
| Chhota Tawa | |
| Kundi, Goi, Karjan |
Major Dams / Projects
- Sardar Sarovar Dam (Gujarat)
- Indira Sagar Dam
- Omkareshwar Dam
- Maheshwar Dam
Key Basin Features
- Rift Valley Formation (structural control)
- Red & Black Soils
- Rich in Forest Resources
- Important for Irrigation, Hydropower & Drinking Water
2. TAPI (TAPTI) RIVER
(Major West-Flowing River | Parallel to Narmada)
The Tapi River originates in the Betul district (Madhya Pradesh) and flows westward parallel to the Narmada before draining into the Arabian Sea. It forms a rift valley along the Satpura Range and is often called the “Twin of Narmada” and mythologically the “Daughter of Surya.” The Tapi basin has more tributaries on the Left Bank, draining a larger catchment area.
Major Tributaries
| Left Bank Tributaries | Right Bank Tributaries |
| Purna (Largest) | Gomai |
| Girna | Aner |
| Panjhra | Arunavati |
| Bori | Vaki |
| Waghur | |
| Amravati |
Major Dams
- Ukai Dam (Gujarat)
- Kakrapar Dam (Gujarat)
Basin Characteristics
- Dominated by Black Cotton Soil (Regur Soil)
- Important for Cotton & Agriculture
- Supports Industrial Corridors in Gujarat & Maharashtra
3. MAHI RIVER
(Inter-State West-Flowing River | 583 km)
The Mahi River originates from Mehad Lake in the Vindhyachal Hills (Dhar district, Madhya Pradesh) and flows through Madhya Pradesh, Rajasthan and Gujarat before draining into the Gulf of Khambhat. It is unique as the only river in India that crosses the Tropic of Cancer twice.
Major Tributaries
| Left Bank | Right Bank |
| Anas | Som |
| Panam | Bhadar |
| Goma | Moran |
| Kun |
Major Dams / Structures
- Mahi Bajaj Sagar (Rajasthan)
- Kadana Dam (Gujarat)
- Panam Reservoir
- Wanakbori Weir
Basin Features
- Rich in Titanium, Iron & Chromium sediments
- Supports Irrigation & Hydropower
- Important inter-state water management river
