Anyone familiar with my postings and with work on the rise of the sea level coincident with the dissolution of the northern Ice Age knows that the
was hugely inundated.
This work has pieced together the ground evidence and notes the abrupt emergence of ‘coastal’ communities at the same time some 8000 years ago. It is natural to conclude that a large settled population was driven out and during the period in which the massive melt water sea collapsed rather abruptly by sudden flooding.
All this is presaged in biblical accounts that speak to us from the late Bronze Age, even though the final submergence took place around 8,000 years ago by this reckoning.
A more important observation is that the Persian Gulf can actually be sealed off and slowly drained to restore a premium agricultural region the size of
. The choke point at the Britain Strait
of Hormuz is around 60 kilometers across and the depth does not
exceed ninety meters or around three hundred feet.
The sea evaporates more water than it receives by way of its river systems and actually produces a brine outflow while receiving replenishment from the
Actual damming with massive earthen dams is quite practical and should be done with two widely separated dams to provide an internal hydraulic lock that naturally prevents any undermining and connection. This could be progressively filled to sea level and plausibly occupied with a mangrove swamp to completely stabilize the blockage of the strait. This is a huge undertaking but that is now within our capacity.
Sea will then begin to decline quite
rapidly opening up fresh sea bed every year that can be progressively watered
by irrigation of the available riverine waers and perhaps new flows caused by
application of the ‘ ’
machine that I have posted on in the past. Eden
I would do one other thing in this case and that is to pump deep brine out of the sea into the
Ocean. In this manner we
will not have a remnant dead sea that is impossible to work with. Once the entire sea has been stabilized at a
level in which evaporation matches actual fresh water inflow then such
extraction will become fairly minor in order to maintain sweetness. The remnant sea should be rather small since
most of the river water will feed irrigation and its natural evaporation.
What can be created is a naturally enclosed basin that is never bothered by severe weather and is an optimal growing environment for high yield agriculture, not unlike the

Lost Civilization May Have Existed Beneath the

Veiled beneath the Persian Gulf, a once-fertile landmass may have supported some of the earliest humans outside
Africa some 75,000 to 100,000 years ago, a new review of
At its peak, the floodplain now below the Gulf would have been about the size of
, and then shrank as
water began to flood the area. Then, about 8,000 years ago, the land would have
been swallowed up by the Great Britain Indian Ocean, the
review scientist said.
The study, which is detailed in the December issue of the journal Current Anthropology, has broad implications for aspects of human history. For instance, scientists have debated over when early modern humans exited Africa, with dates as early as 125,000 years ago and as recent as 60,000 years ago (the more recent date is the currently accepted paradigm), according to study researcher Jeffrey Rose, an archaeologist at the University of Birmingham in the U.K.
"I think Jeff's theory is bold and imaginative, and hopefully will shake things up," Robert Carter of
University in the told LiveScience. "It
would completely rewrite our understanding of the out-of-Africa migration. It
is far from proven, but Jeff and others will be developing research programs to test the theory." U.K.
Viktor Cerny of the Archaeogenetics Laboratory, the Institute of Archaeology, in Prague, called Rose's finding an "excellent theory," in an e-mail to LiveScience, though he also points out the need for more research to confirm it.
The findings have sparked discussion among researchers, including Carter and Cerny, who were allowed to provide comments within the research paper, about who exactly the humans were who occupied the Gulf basin.
"Given the presence of Neanderthal communities in the upper reaches of the Tigris and Euphrates River, as well as in the eastern Mediterranean region, this may very well have been the contact zone between moderns and Neanderthals," Rose told LiveScience. In fact, recent evidence from the sequencing of the Neanderthal genome suggests interbreeding, meaning we are part caveman.
The Gulf Oasis would have been a shallow inland basin exposed from about 75,000 years ago until 8,000 years ago, forming the southern tip of the Fertile Crescent, according to historical sea-level records.
And it would have been an ideal refuge from the harsh deserts surrounding it, with fresh water supplied by the Tigris, Euphrates, Karun and Wadi Baton Rivers, as well as by upwelling springs, Rose said. And during the last ice age when conditions were at their driest, this basin would've been at its largest.
In fact, in recent years, archaeologists have turned up evidence of a wave of human settlements along the shores of the Gulf dating to about 7,500 years ago.
"Where before there had been but a handful of scattered hunting camps, suddenly, over 60 new archaeological sites appear virtually overnight," Rose said. "These settlements boast well-built, permanent stone houses, long-distance trade networks, elaborately decorated pottery, domesticated animals, and even evidence for one of the oldest boats in the world."
Rather than quickly evolving settlements, Rose thinks precursor populations did exist but have remained hidden beneath the Gulf.
"Perhaps it is no coincidence that the founding of such remarkably well developed communities along the shoreline corresponds with the flooding of the
basin around 8,000 years ago," Rose said. "These new colonists may
have come from the heart of the Gulf, displaced by rising water levels that
plunged the once fertile landscape beneath the waters of the Indian
The most definitive evidence of these human camps in the Gulf comes from a new archaeological site called Jebel Faya 1 within the Gulf basin that was discovered four years ago. There, Hans-Peter Uerpmann of the
University of Tubingen in found three different
Paleolithic settlements occurring from about 125,000 to 25,000 years ago. That
and other archaeological sites, Rose said, indicate "that early human
groups were living around the Gulf basin throughout the Late Pleistocene." Germany
To make an ironclad case for such human occupation during the Paleolithic, or early Stone Age, of the now-submerged landmass, Rose said scientists would need to find any evidence of stone tools scattered under the Gulf. "As for the Neolithic, it would be wonderful to find some evidence for human-built structures," dated to that time period in the Gulf, Rose said.
Carter said in order to make for a solid case, "we would need to find a submerged site, and excavate it underwater. This would likely only happen as the culmination of years of survey in carefully selected areas."
Cerny said a sealed-tight case could be made with "some fossils of the anatomically modern humans some 100,000 years old found in
And there's a hint of mythology here, too, Rose pointed out. "Nearly every civilization living in southern
Mesopotamia has told some form of the flood myth. While
the names might change, the content and structure are consistent from 2,500
B.C. to the Genesis account to the Qur'anic version," Rose said.
Perhaps evidence beneath the Gulf? "If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family Anatidae on our hands," said Rose, quoting Douglas Adams.
This inland sea of some 251,000 km² is connected to the Gulf of Oman in the east by the Strait of Hormuz; and its western end is marked by the major river delta of the Shatt al-Arab, which carries the waters of the Euphrates and the Tigris. Its length is 989 kilometres, with Irancovering most of the northern coast and Saudi Arabia most of the southern coast. The Persian Gulf is about 56 kilometres wide at its narrowest, in the Strait of Hormuz. The waters are overall very shallow, with a maximum depth of 90 metres and an average depth of 50 metres.
