River Basins in India

12 major river basins have an area of 20,000 km² and more, namely

  • Brahmaputra River Basin includes the states of Arunachal Pradesh, Assam, West Bengal, Meghalaya, Nagaland, and the entire state of Sikkim. It is known as the greenest part of India.
  • Cauvery River Basin – covers the states of Tamil Nadu, Karnataka, Kerala, and the Union Territory of Puducherry. River Cauvery flows into the Bay of Bengal. Alluvial soils characterize the delta areas.
  • Godavari River Basin - includes the states of Maharashtra, Andhra Pradesh, Chhattisgarh, and Odisha. During the southwest monsoon, the Godavari basin receives the most rainfall.
  • Indus River Basin – Covers the states of Jammu and Kashmir, Himachal Pradesh, Punjab, and part of Rajasthan, Haryana, and the Union Territory of Chandigarh. Agricultural land covers most of the watershed, and snowmelt contributes to its massive water flow. .
  • Krishna River Basin – extends across Andhra Pradesh, Maharashtra and Karnataka and is characterized by the Deccan Traps in the northwest, undifferentiated crystals in the center, and the Cuddapah Group in the east.
  • Mahanadi River Basin – extends over large areas of Chhattisgarh and Odisha, as well as smaller parts of Jharkhand, Maharashtra, and Madhya Pradesh. Deltaic soil is found in the Mahanadi coastal plains.
  • Mandovizuari River Basin - Mandovi and Zuari waters are widely used for drinking and agricultural purposes. Mandovi also serves as an important inland navigation route for commercial purposes. Panaji, the state capital, and Old Goa, the former capital of Goa, are located on the left bank of the Mandovi.
  • Narmada River Basin – Located at the northernmost tip of the Deccan Plateau, the basin includes significant areas in the states of Madhya Pradesh and Gujarat and a smaller area in Maharashtra and Chhattisgarh. The mountainous areas are located in the higher elevations of the basin, while the lower middle reaches are wide and fertile soils suitable for agriculture.
  • Pamba River Basin - The Pamba River originates at an altitude of 1,650 m in the Peermade Plateau in the Idukki district of Kerala and, after covering a distance of 176 km, joins the Arabian Sea, branching into a series of channels. The basin covers an area of 2235 km2. The entire catchment area lies in the state of Kerala.
  • Tapi River Basin - The basin extends over the states of Madhya Pradesh, Maharashtra, and Gujarat. The area is characterized by basaltic terrain with plateaus, escarpments, hills, foothills, colluvial alluvial plains, and valley plains as important physiological units.
  • Ganges Basin – Madhya Pradesh, Uttar Pradesh, West Bengal, Rajasthan, Bihar, Uttarakhand, Haryana, Jharkhand, Himachal Pradesh, Chhattisgarh, and Delhi are the 11 basin states of the Ganges. All rivers in the Ganga basin experience annual flooding.
  • Mahi – Covers the states of Madhya Pradesh, Rajasthan, and Gujarat. The Mahi is one of India's major west-flowing interstate rivers.
