The Indus or Sindhu, a major river flowing
through Pakistan around which the great Indus Valley Civilisation flourished,
may have shifted course after an earthquake in 1819, but recent satellite
images show the river has re-entered India feeding a lake near Ahmedabad known
as Nal Sarovar.
The discovery has been made by Rohan Thakkar,
a postgraduate student of climate change working on the water bodies of
The development will hugely benefit the
water-starved Kutch region as well as the Bhal region adjoining Ahmedabad
Speaking to Mail Today, Rohan said he spoke
to his father about it after detecting that water from a river in Pakistan was
flowing into the Rann of Kutch. Further examination of the satellite images
showed the water was flowing from the Indus.
Rohan's father Dr P. S. Thakkar, who is a
satellite archaeologist with the Indian Space Research Organisation, said the
river started flowing into India last year when the Indus river basin was
"Heavy rains had
left the river basin along with the Mancher, Hemal and Kalri lakes inundated
and people breached several canal heads," Thakkar said.
Sindhu changes course
happened this year too. In September, water from the river reached the Great
Rann of Kutch," Thakkar said.
After inundating the Great Rann, water
reached the Little Rann and then Viramgam near Ahmedabad on September 19.
entered India near Vighokot in the Great Rann of Kutch and also through the old
Naraka course, through which the Indus used to flow into the Great Rann of
Kutch before the 1819 earthquake," Thakkar
According to the archaeologist, the volume of
water was so much that it inundated both the Great Rann and Little Rann, and
travelled nearly 500km to Viramgam this year.
Dr Y. T. Jasrai, programme coordinator of the
climate control department at Gujarat University, said the phenomenon had been
taking place for some time.
"We do have
evidence that there were habitations in the Rann of Kutch and the Indus flowed
in this area but majorly shifted its course westwards after the great
earthquake in 1819," Thakkar said.
are signs that the river is steadily shifting its course, siltation in the
Indus river basin too could be responsible for the change in course," Rohan said.
"At that time, one of the
major branches of the Indus was emptying its water into the Great Rann of
Kutch," he added.
after the 1819 quake, the Allahbund came up in the northwest of Bhuj as a
natural bund and stopped the water from flowing into the Great Rann of Kutch
and the area gradually dried up. Successively, the river too changed its
course," Ravat added.
nothing surprising if the river now starts shifting eastwards," he said.
