willedoo Posted August 10, 2022 Posted August 10, 2022 49 minutes ago, old man emu said: In 1997, William Ryan, Walter Pitman, Petko Dimitrov, and their colleagues first published the Black Sea deluge hypothesis, that a catastrophic inflow of Mediterranean seawater into the Black Sea freshwater lake occurred around 7600 years ago. As proposed, the Black Sea flood scenario describes events that would have profoundly affected prehistoric settlement in eastern Europe and adjacent parts of Asia and possibly was the basis of oral history concerning Noah's flood. Some archaeologists support this theory as an explanation for the lack of Neolithic sites in northern Turkey. Don't tell that to Putin. He'll want to claim the Mediterranean as well if he hears about that one. 2 1 1
facthunter Posted August 11, 2022 Posted August 11, 2022 There's also a canal from the south of France to the English Chanel but canals don't drain or transfer water to or from oceans. They have locks that are fed by fresh water that raise the Boats to get over rising terrain. Nev 1 1 1
Bruce Tuncks Posted August 20, 2022 Posted August 20, 2022 (edited) I can imagine a canal that took water from an ocean to keep it at high tide level. The port road in Adelaide is super-wide, the story is that there was going to be a canal there. But the land rises to the east, and any canal at tide-level would be very low at the top of the port road. About 150 feet low. And I don't think the Torrens river would have had enough water to keep a series of locks running. This is a bit sad... apparently many German immigrants perished on the way up the port road. I imagine them weakened from the inactivity and maybe malnutrition of the voyage, and wearing their stupid puritan type clothes, taking 2 or 3 goes to carry all their gear in the heat of an Adelaide summer. They could not afford a bullock-wagon. A canal sure would have helped them. They finally got to Klemzig and ended up working for George Fife Angas in the Barossa Valley.

facthunter Posted August 20, 2022 Posted August 20, 2022 If the lock was not too long you'd be able to pump the water from downstream and re use it over and over. A Dry dock is sunk then the ship floats in and the the dry dock has the water pumped out to raise the ship a above water level to effect repairs.. Newcastle NSW had one. Nev 2
