Indian River

1. Ganga River

The Ganges or Ganga, is a trans-boundary river of India andBangladesh.

The 2,525 km (1,569 mi) river rises in the western Himalayas in the Indian state of Uttarakhand, and flows south and east through the Gangetic Plain of North India into Bangladesh, where it empties into the Bay of Bengal. It is the longest river of India and is the second greatest river in the world by water discharge. The Ganges basin is the most heavily populated river basin in the world, with over 400 million people and a population density of about 1,000 inhabitants per square mile

The Ganges was ranked among the five most polluted rivers of the world in 2007, with fecal coliform levels in the river nearVaranasi more than one hundred times the official Indian government limits. Pollution threatens not only humans, but also more than 140 fish species, 90 amphibian species and the endangered Ganges river dolphin. The Ganga Action Plan, an environmental initiative to clean up the river, has been a major failure thus far, due to corruption and lack of technical expertise,lack of good environmental planning, Indian traditions and beliefs, and lack of support from religious authorities

2. Yamuna River

The Yamuna, sometimes called Jamuna or Jumna, is the largest tributary river of the Ganges (Ganga) in northern India. Originating from the Yamunotri Glacier at a height of 6,387 metres on the south western slopes of Banderpooch peaks in the Lower Himalayas in Uttarakhand, it travels a total length of 1,376 kilometers (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganges Basin, before merging with the Ganges at Triveni Sangam, Allahabad, the site for the Kumbha Mela every twelve years. 

3. Brahmaputra River

The Brahmaputra also called Tsangpo-Brahmaputra, is a trans-boundary river and one of the major rivers of Asia.

With its origin in the Angsi Glacier, located on the northern side of the Himalayas in Burang County of China's Tibet Autonomous Region as the Yarlung Tsangpo River, it flows across southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh (India) where it is known as Dihang orSiang. It flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna (not to be mistaken with Yamuna of India). In the vast Ganges Delta it merges with the Padma, the main distributary of theGanges, then the Meghna, before emptying into the Bay of Bengal. About 1,800 miles (2,900 km) long, the Brahmaputra is an important river for irrigation and transportation. The average depth of the river is 124 feet (38 m) and maximum depth is 380 feet (120 m). The river is prone to catastrophic flooding in spring when the Himalayan snows melt. The average discharge of the river is about 19,300 cubic metres per second (680,000 cu ft/s), and floods can reach over 100,000 cubic metres per second (3,500,000 cu ft/s).[6] It is a classic example of a braided river and is highly susceptible to channel migration and avulsion.[7] It is also one of the few rivers in the world that exhibit a tidal bore. It is navigable for most of its length.

4. Krishna River

The Krishna River is one of the longest rivers in central-southern India, about 1,400 kilometres (870 mi). It is also referred to as Krishnaveni in its original nomenclature. The Krishna River is the third longest river in India after the Ganges nd theGodavari.

Krishna river rises at Mahabaleswar near the Jor village in the extreme north of Wai Taluka, Satara District, Maharashtra in the west and meets the Bay of Bengal at Hamasaladeevi (near Avanigadda) in Andhra Pradesh, on the east coast. It flows through the state of Karnataka before entering Andhra Pradesh. The delta of this river is one of the most fertile regions inIndia and was the home to ancient Satavahana and Ikshvaku Sun Dynasty kings. Vijayawada is the largest city on the River Krishna. Sangli is the largest city on the river Krishna in Maharashtra state.

5. Godavri River

The Godavari is a river in the south-central India. It starts in the western state of Maharashtra and flows through the Southern state of Andhra Pradesh before reaching the Bay of Bengal. It forms one of the largest river basins in India. With a length of 1465 km, it is the second longest river in India,second to The Ganges, and the longest in southern India. It originates near Trimbak in Nashik District of Maharashtra state. It flows east across the Deccan Plateau into the Bay of Bengal nearYanam and Antarvedi in East Godavari district of Andhra Pradesh. The Godavari is a major waterway in central India, originating in the Western Ghats Trimbakeshwar, in the Nashik Subdivision or District Of Maharashtra and flowing eastwardly across the Deccan Plateau through the state of Maharashtra. It is known as dakshin ganga (Southern Ganges) because it originates from river Ganga (underground water) near Trimbak in Nashik.

6. Narmada River

The Narmada (Devanagari: नर्मदा, Gujarati: નર્મદા)

, also called the Rewa, is a river in central India and the fifth longest river in theIndian subcontinent. It is the third longest river that flows entirely within India, after the Godavari and the Krishna. It forms the traditional boundary between North India and South India and flows westwards over a length of 1,312 km (815.2 mi) before draining through the Gulf of Khambhat into the Arabian Sea, 30 km (18.6 mi) west of Bharuch city of Gujarat.[1] It is one of only three major rivers in peninsular India that run from east to west (longest west flowing river), along with the Tapti River and the Mahi River.

It is the only river in India that flows in a rift valley, flowing west between the Satpura and Vindhya ranges. The Tapti River and Mahi River also flow through rift valleys, but between different ranges. It flows through the states of Madhya Pradesh (1,077 km (669.2 mi)), and Maharashtra, (74 km (46.0 mi))– (35 km (21.7 mi)) then along the border between Madhya Pradesh andMaharashtra and (39 km (24.2 mi) and the border between Madhya Pradesh and Gujarat and in Gujarat 

7. Tapi River

The Tapti River (Hindi ताप्ती, Marathi तापी, Gujarati: તાપ્તી) ancient original name Tapi River (Sanskrit: तापी), is a river in central India. It is one of the major rivers of peninsular India with a length of around 724 kilometres (450 mi). It is one of only three rivers in peninsular India that run from east to west - the others being the Narmada River and the Mahi River. The river rises in the eastern Satpura Range of southern Madhya Pradesh state, and flows westward, draining Madhya Pradesh's Nimar region, Maharashtra's Kandesh and east Vidarbha regions in the northwest corner of the Deccan Plateau and south Gujarat, before emptying into the Gulf of Cambay of the Arabian Sea, in the Surat District of Gujarat. The river, along with the northern parallel Narmada river, form the boundaries between North and South India. The Western Ghats or Sahyadri range starts south of the Tapti River near the border of Gujarat and Maharashtra. The Tapti (Tapi) River empties into the Gulf of Khambhat near the city of Surat in Gujarat.
