Ages from zircons sampled across the region ensured that the deposits were the same age despite being separated by a great distance.The delta “is essentially 10 times bigger than the modern Amazon delta or the Ganges in India. The Volga Delta has grown significantly over the past 130 years. “You can use ancient deltas to understand how modern river systems should be behaving.”But this same propensity for humans to congregate around deltas makes it more difficult for scientists to study how they naturally grow and change. Over the past century, the Volga Delta has grown from 3,222 square kilometers (1,244 square miles) in 1880 … “There are likely pieces of the puzzle that still need to be added this story,” he added.

The Ganges Delta empties into the Bay of Bengal and stretches from the Hooghly River to the Meghan River. But “you can use ancient deltas to understand how modern river systems should be behaving,” he said. “As you move down the delta plain and start affecting it with tides and standing water, the channels split and evolve and are dancing around on the delta plain much like we see today,” Klausen said. It is Europe’s largest river delta, situated where the Volga pours its fresh water and sediment into the northwest sector of the Caspian Sea. The team measured past seafloor depths—paleobathymetry—and found that the delta emptied into a very large basin only about 400 meters deep. The largest delta plain in Earth's … It is found on the border of Russia and China. One third of the delta lies in India, and all waters flow into the Bay of Bengal. This study’s detailed seismic reflection data “allow unprecedented documentation of large-scale depositional systems from Paleozoic to modern times,” according to Miller, who was not involved with this research. Over the past century, the Volga Delta has grown from 3,222 square kilometers (1,244 square miles) in 1880 to 27,224 square kilometers (10,511 square miles) today. Credit: Tore Grane Klausen.

Deltas can support large-scale agriculture and have sustained some of the largest ancient civilizations. “One of the things that we’re really excited to look at in the future is what role this massive delta had in evolution and the resurgence of both terrestrial and marine life,” he said. Its far northern location keeps the Lena River Delta frozen for as long as seven months of the year, but during the short summer, it thaws into a wetland of tremendous ecological importance. A large supply of sediment, monsoon-like rainfalls, and steady sea levels all contributed to the delta’s growth, the researchers said, but the shallow basin was the key to its gargantuan size. The delta is the floodplain of three rivers including Ganges, Megna, and Brahmaputra with the three rivers draining a catchment of about 665,000 square miles on the southern side of the Himalaya. The Mississippi River is the largest river system in North America. Fishing is also a major economic activity in the Ganges Delta.
