Saraswati: The lost river of India

Missing of a prominent river from the map is not a mystery; it is quite natural as the natural phenomena evolve through environmental changes. 

A part of the river Saraswati till now exists as Ghaggar in Haryana, the rest of it has disappeared in the fringes of the Marusthali or the Thar Desert. 

Bhabha Atomic Research Centre, Mumbai has made a breakthrough in its research for the existence and probable location of the mythical Saraswati river. The Rajasthan Ground Water Department undertook the task to ‘unearth’ the river with the collaboration of BARC and Physical Research Laboratory, Ahmedabad (a wing of ISRO) in 1998. 

If the effort is successful, the people living in the desert belt of Rajasthan will be hopefully supplied more than 3500 year old water derived from palaeo-channels, believed to be the mythical Saraswati. 

Being one of the chief Rigvedic Rivers, as per the Hindu scripts and texts, Saraswati River is also famously known as Ghaggar-Hakra River. The Saraswati River is mentioned between the east of Yamuna and west of Sutlej in the early Rigvedic 'Nadistuti' hymn.
But later in the other Vedic scriptures it is said that the Saraswati River dried up in a desert. This river is a trans-boundary to India as well as to Pakistan. Also this river flows through both the nations together only in the monsoon.
          Several palaeo-channels of river have been identified in the region of Rajasthan, Haryana, Uttar Pradesh and adjacent areas, some of which are assigned to the Saraswati. The river is considered to have migrated from east to west. But in the past, most discussions have pointed to the river being in north Gujarat.
Course of Sarasvati river
 Geological record indicates that during the late Pleistocene glaciation, the water of the Himalayas was frozen and that in the place of rivers, there were only glaciers, masses of solid ice. When the climate became warmer, the glaciers began to break up and the frozen water held by them surged forth in great floods, inundating the alluvial plains in front of the mountains. The melting of glaciers has also been referred in Rig Vedic literature, in mythological terms. It was the first interglacial period in Holocene marking the break-up of glaciers and release of the pent-up waters that flowed out in seven mighty river channels referred as the ‘Sapta Sindhu’ in the Rig Veda, traced from east to west. The ‘Sapta Sindhu’ refers to the rivers Saraswati, Satadru (Sutlej), Vipasa (Beas), Asikni (Chenab), Parosni (Ravi), Vitasta (Jhelum) and Sindhu (Indus). Among these, the Saraswati and the Sindhu were major rivers that flowed from the mountains right up to the sea. The hymns in praise of the Saraswati are probably some of the oldest, composed more than 8000 years ago.

For 2000 years, between 6000 and 4000 B.C., the Saraswati flowed as a great river. R. D. Oldham (1886) was the first geologist who argued logically pointing to the great changes in the drainage pattern of the rivers of Punjab and western Rajasthan converting a once fertile region into a desert. According to geological and glaciological studies, the Saraswati was supposed to have originated in Bandapunch massif (Saraswati-Rupin glacier confluence at Naitwar in western Garhwal).

 The river, which had originated from Kapal tirith in the Himalayas in the west of Kailash, was flowing southward to Mansarovar and then taking a turn towards west. Even today the Saraswati flows from the south of Mana pass which meets river Alaknanda, 3 km away in the south of Mana village. Descending through Adibadri, Bhavanipur and Balchapur in the foothills to the plains, the river took roughly a southwesterly course, passing through the plains of Punjab, Haryana, Rajasthan, Gujarat and finally it is believed to have debounched into the ancient Arabian Sea at the Great Rann of Kutch. In this long journey, the Saraswati is believed to have had three tributaries, Shatadru (Sutlej) originating from Mount Kailas, Drishadvati from Siwalik Hills and the old Yamuna. They flowed together along a channel, presently known as the Ghaggar River, which is known as Hakra River in Rajasthan and Nara in Sindh. Some experts consider these two rivers as a single river whereas others consider the upper course of the Saraswati as Ghaggar and the lower course as the Hakra River, while some others call the Saraswati of the weak and declining stage as the Ghaggar.

 The river was obliterated within a short span, in the Quarternary period of the Cenozoic era, through a combination of destructive catastrophic events. The decline of the river appears to have commenced between 5000 and 3000 B.C., probably precipitated by a major tectonic event in the Siwalik Hills of Sirmur region. Geological studies reveal that the massive landslides and avalanches were caused by destabilising tectonic events which occurred around the beginning of Pleistocene, about 1.7 million years ago in the entire Siwalik domain, extending from Potwar in Pakistan to Assam in India. Those disturbances, linked to uplift of the Himalayas, continued intermittently. Presumably, one of these events must have severed the glacier connection and cut off the supply of melt water from the glacier to this river; as a result, the Saraswati became non-perennial and dependent on monsoon rains. The diversion of the river water through separation of its tributaries led to the conversion of the river as disconnected lakes and pools; ultimately it was reduced to a dry channel bed. Therefore, the river Saraswati has not disappeared but only dried up in some stretches.

Etymology : Sarasvatī is the devi feminine of an adjective sarasvant- (which occurs in the Rigveda as the name of the keeper of the celestial waters), derived from Proto-Indo-Iranian *sáras-vant-ī (and earlier, PIE *séles-u̯n̥t-ih₂), meaning ‘marshy, full of pools’.
Sanskrit sáras means ‘pool, pond’; the feminine sarasī́ means ‘stagnant pool, swamp’. Like its cognates Welsh hêl, heledd ‘river meadow’ and Greek ἕλος (hélos) ‘swamp’, the Rigvedic term refers mostly to stagnant waters, and Mayrhofer considers unlikely a connection with the root *sar- ‘run, flow’.
Sarasvatī is an exact cognate with Avestan Haraxvatī, perhaps originally referring to Arədvī Sūrā Anāhitā (modern Ardwisur Anahid), the Zoroastrian mythological world river, which would point to a common Indo-Iranian myth of a cosmic or mystical Sáras-vant-ī river. In the younger Avesta, Haraxvatī is Arachosia, a region described to be rich in rivers, and its Old Persian cognate Harauvati, which gave its name to the present-day Hārūt River in Afghanistan, may have referred to the entire Helmand drainage basin (the center of Arachosia).
