Ganga River in India

 

The Ganges (English pronunciation:or Ganga,  is a trans-boundary river of India and Bangladesh. 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. By discharge it ranks among the world's top 20 riversThe 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 (390 /km²).
The Ganges is the most sacred river to Hindus and is also a lifeline to millions of Indians who live along its course and depend on it for their daily needsIt is worshiped as the goddess Ganga in Hinduism.It has also been important historically: many former provincial or imperial capitals (such as Patliputra,Kannauj, Kara, Kashi, Allahabad, Murshidabad, Munger, Baharampur and Kolkata) have been located on its banks.
The Ganges ranks among the top five most polluted rivers of the world with fecal coliform levels in the river near Varanasi more than 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.

History

The Late Harappan period, about 1900–1300 BCE, saw the spread of Harappan settlement eastward from the Indus River basin to the Ganges-Yamuna doab, although none crossed the Ganges to settle its eastern bank. The disintegration of the Harappan civilization, in the early 2nd millennium BC, marks the point when the center of Indian civilization shifted from the Indus basin to the Ganges basin.There may be links between the Late Harappan settlement of the Ganges basin and the archaeological culture known as "Cemetery H", the Indo-Aryan people, and the Vedic period.
This river is the longest in India. During the early Vedic Age of the Rigveda, the Indus and the Sarasvati River were the major sacred rivers, not the Ganges. But the later three Vedas give much more importance to the Ganges. The Gangetic Plain became the cradle of successive civilizations, from the Maurya Empire to the Mughal Empire.
The first European traveler to mention the Ganges was Megasthenes (ca. 350–290 BCE).He did so several times in his work Indica: "India, again, possesses many rivers both large and navigable, which, having their sources in the mountains which stretch along the northern frontier, traverse the level country, and not a few of these, after uniting with each other, fall into the river called the Ganges. Now this river, which at its source is 30 stadia broad, flows from north to south, and empties its waters into the ocean forming the eastern boundary of the Gangaridai, a nation which possesses a vast force of the largest-sized elephants." (Diodorus II.37) In the rainy season of 1809, the lower channel of the Bhagirathi, leading to Kolkata, had been entirely shut; but in the following year it opened again, and was nearly of the same size with the upper channel; both however suffered a considerable diminution, owing probably to the new communication opened below the Jalanggi. On the upper channel.
In 1951 a water sharing dispute arose between India and Bangladesh (then East Pakistan), after India declared its intention to build the Farakka Barrage. The original purpose of the barrage, which was completed in 1975, was to divert up to 40,000 cu ft/s (1,100 m³/s) of water from the Ganges to the Bhagirathi-Hooghly distributary in order to restore navigability at the Port of Kolkata. It was assumed that during the worst dry season the Ganges flow would be around 50,000 to 55,000 cu ft/s (1,400 to 1,600 m³/s), thus leaving 10,000 to 15,000 cu ft/s (280 to 420 m³/s) for East Pakistan East Pakistan objected and a protracted dispute ensued. In 1996 a 30-year treaty was signed. The terms of the agreement are complicated, but in essence they state that if the Ganges flow at Farakka was less than 70,000 cu ft/s (2,000 m³/s) then India and Bangladesh would each receive 50% of the water, with each receiving at least 35,000 cu ft/s (990 m³/s) for alternating ten day periods. However, within a year the flow at Farakka fell to levels far below the historic average, making it impossible to implement the guaranteed sharing of water. In March 1997, flow of the Ganges in Bangladesh dropped to its lowest ever, 6,500 cu ft/s (180 m³/s). Dry season flows returned to normal levels in the years following, but efforts were made to address the problem. One plan is for another barrage to be built in Bangladesh at Pangsha, west of Dhaka. This barrage would help Bangladesh better utilize its share of the waters of the Ganges
