In the book of Rig Veda chapter number 10.92.2 it is clearly mentioned (say it with voice of Zakir Naik) that Sarasvati rose from the mountains and fell into the ocean. And the study in the OP which i am sure you didn't bother to read anyway clearly say that Ghaggar-Hakra is monsoon-fed river. Now run away and hide, and its not me but respect full Tamils (unlike our wannabe aunty on PDF) saying it that they are portrayed as monkeys.
You were talking talking about this research.
The report is not claiming that Ghaggar-Hakra was not Saraswati.
Monsoon link to end of Harappan cities

New Delhi, May 28: The ancient Harappan civilisation emerged, flourished, and collapsed under a steadily weakening monsoon, according to new research findings that scientists say provide the strongest evidence yet to link its rise and fall to changing climate.
An international team of scientists has combined multiple sets of data to show that weakening monsoon and reduced river water initially stimulated intensive agriculture and urbanisation, but later precipitated the decline and collapse of the subcontinent’s earliest cities.
The scientists said their research also suggests that a large river, assumed to be the mythical Saraswati, which once watered the Harappan civilisation’s heartland between the Indus and the Ganges basins was a monsoon-fed river — contrary to interpretations of text from the Rig Veda that suggests it was a glacier-fed river with origins in the Himalayas.
Their findings appear today in the US journal Proceedings of the National Academy of Sciences.
“The link between a weakening monsoon and the fate of the Harappan civilisation should now be considered as settled,” said Ronojoy Adhikari, a physicist with the Institute of Mathematical Sciences, Chennai, a research team member.
“We can now almost rule out every other hypothesis that has ever been proposed for the decline of urbanism in the Harappan heartland,” said Adhikari, who used statistical tools to analyse changing urban patterns in the region from 7000 BC to 500 BC.
Adhikari and his colleagues from Pakistan, Romania, the UK, and the US combined evidence from archaeology, geology, and satellite photos to develop a chronology of landscape changes in the region spanning nearly 10,000 years.
Their analysis shows that the emergence of settlements coincided with a steady weakening of the monsoon that began about 5,000 years ago. The Harappans took advantage of a window in time during which a weakening monsoon encouraged settlements.
“It was a kind of a Goldilocks civilisation,” said Liviu Giosan, a geologist and principal of the study at the Woods Hole Oceanographic Institution in the US. “During periods of heavy rains, the floods were too wild for people to settle near rivers, it was too dangerous.”
As the monsoon rains weakened, a gradual decrease in the intensity of floods stimulated the intensive agriculture and encouraged urbanisation about 4,500 years ago. But the continued decline in monsoon rainfall began to drive people to wetter regions upstream and eastward.
“As rivers became increasingly drier, going east became an escape route,” Giosan told The Telegraph. The archaeological record shows that settlements shifted eastward, but the region did not support crop surpluses that the Harappans had enjoyed in their river valleys.
“They forgot their (Harappan) script, and concentrated on survival,” Giosan said.
Archaeologists believe it might have been during these times of decline that the Harappan civilisation developed one of its great legacies — the double-cropping system with kharif and rabi crop rotations that survives in the subcontinent even today.
“It is clear that while winter crops were Harappan staples, the Harappan period also saw diversification of agriculture, including a range of summer millets and grams,” said Dorian Fuller, an archaeologist and team member at the University College, London.
“And these crops could have been grown independent of any river system during the monsoon rains, but only in the eastern part of the Harappan realm. Archaeobotanical evidence points to an increasing balance between these summer and winter crops in the late Harappan period,” Fuller told The Telegraph.
“Small farmers chose sustainability in the eastern Harappan lands rather than continue in cities like Harappa.”
Giosan said the findings show how changing climate may influence the fate of people and cultures. “If the monsoon were to increase in a warmer world, as some predict, catastrophic floods could turn the current irrigation system, designed for a tamer river, obsolete.”
The new geological evidence also suggests that the Ghaggar-Hakra river network, assumed by some as the mythical Saraswati, was not fed by a Himalayan glacier, but was a monsoon-fed river whose flow turned from perennial to seasonal under the weakening monsoon.
The Rig Veda refers to a mighty Saraswati that flowed through the year and joined the sea, said Adhikari, but those who compiled the Vedas may have had insufficient knowledge of the full geography of the river. “It is possible that they thought of it in analogy with the Indus, which does indeed rise in the mountains,” he said.
Three years ago, a team of scientists from the Geological Survey of India and the University of Delhi had used chemical analysis of sediments to show that the Ghaggar-Hakra river was not glacier-fed. “This new study adds geomorphological evidence,” Adhikari said.
The incisions the Ghaggar-Hakra has made in the landscape lacks the signatures of a glacier-fed river.
Why don't you stick with Tamil language which is "pure".
is an archaeological site in Bhachau Taluka of Kutch District, in the state of Gujarat in western India, which has taken its name from a modern village 1 km (0.62 mi) south of it. Also known locally as Kotada timba the site contains ruins of an ancient Indus Valley Civilization /Harappan city. It is one of the five largest Harappan sites [1] and most prominent archaeological sites in India belonging to the Indus Valley Civilization . It is also considered as grandest of cities [2] of its time. It is located on the Khadir bet island in the Kutch Desert Wildlife Sanctuary in Great Rann of Kutch and the area of the full site is more than 100 ha (250 acres). [3] The site was occupied from c.2650 BCE, declining slowly after about 2100 BCE. It was briefly abandoned and reoccupied until c.1450 BCE. [4] The site was discovered in 1967-8 by J. P. Joshi and is the fifth largest of eight major Harappan sites. It has been under excavation since 1990 by the Archaeological Survey of India , which opines that "Dholavira has indeed added new dimensions to personality of Indus Valley Civilisation." [5] The other major Harappan sites discovered so far are: Harappa , Mohenjo-daro , Ganeriwala , Rakhigarhi , Kalibangan, Rupnagar and Lothal. source wiki.
