According to some general-knowledge encyclopedias, including the 9t edition of Encyclopedia Britannica published in the late 19th century, “the natives are talking about belowground channels connection Lake Van to the headspring of Tigris River” and “the waters of Lake Nazik flow to both Lake Van and the Euphrates river due to a rare phenomenon”.
One of the researchers of the late 19th century in his publication in an authoritative journal argued that he had discovered a connection between the Euphrates and Lake Van through a passage within Mount Nemrut. These connections remained as theories and gossips, and the next edition of Encyclopedia Britannica published in 1910-1911 no longer contained a mention of them.
Apart from that, at the time it was assumed that the unusual structure of watersheds and the fact of formation of Lake Van itself was a result of a large eruption of Mount Nemrut. Later, this was confirmed by several studies.
According to the authors of the Black Sea deluge hypothesis, William Ryan and Walter Pitman, the Great Flood is based on an actual catastrophic rise in the level of the Black Sea that occurred circa 5600 BC. According to V. Safronov, the global catastrophe caused by rapid melting of glaciers should be dated at 8122 BC.
The data of distribution of sediments in the Black Sea allowed Ryan and Pitman to conclude that 7,000 years ago, the level of the Black Sea rose by about 50 meters, increasing the area of the sea 2 times and forming the Bosphorus. The researchers think that such flooding of expansive areas could play its role in the emergence of legends about a great flood.
At the same time, a maritime archaeologist Robert Bollard argued that he had discovered the confirmation for the Black Sea deluge hypothesis. With the help of robots, Bollard investigated the sunken settlements offshore modern Turkey. The analysis of the gathered data showed that the flood had been instantaneous and that its date corresponds to the Bible. Additional evidence based on the analysis of the Abkhaz mythology featuring accounts of the flood was presented by Lev Regelson and Igor Khvartskiya.
Among the theorized reasons for the catastrophe is the sudden influx of water from the Mediterranean Sea into the Black Sea as a result of an earthquake. The scientists who examined the bottom of the Black Sea dated the changes in sediments and water flora back to circa 5500 BC.
Historians assume that this event was witnessed by the locals. According to the Bible, Noah’s Ark came to rest on Mount Ararat, which could pretty much look like islands among the huge mass of water.
It should be noted that the Black Sea deluge hypothesis caused quite a bit of controversy and is not confirmed at the moment.
