Research has revealed details of the catastrophic Zanclean flood that refilled the Mediterranean Sea more than five million years ago.
The flood occurred when Atlantic waters found their way into the cut-off and desiccated Mediterranean basin.
The researchers say that a 200km channel across the Gibraltar strait was carved out by the floodwaters... show that the resulting flood could have filled the basin within two years.
The team was led by Daniel Garcia-Castellanos from the Research Council of Spain (CSIC)...
Using existing borehole and seismic data, his team showed how the flood would have begun with water spilling over a sill.
The water would have gradually eroded a channel into the strait, eventually triggering a catastrophic flood, Dr Garcia-Castellanos explained.
He and his colleagues created a computer model to estimate the duration of the flood, and found that, when the "incision channel" reached a critical depth, the water flow sped up.
In a period ranging from a few months to two years, the scientists say that 90% of the water was transferred into the basin.
"This extremely abrupt flood may have involved peak rates of sea level rise in the Mediterranean of more than 10m per day," he and his colleagues wrote in the Nature paper.
Previous estimates of the duration of the flood were very variable, said Dr Garcia-Castellanos, because scientists "had to assume the size of the channel" rather than measure it...
Dr Govers said the next important step would be to measure the volume of breccia, or ancient eroded material, in the strait, to confirm whether there was enough material there to have filled the flood channel.

I see a Lords of Atlantis (wallace west)?
So wait, they are saying when the channel gets deeper, more water can move through it? Oh, tell me more.

it may be over your head
then we are clean and we can rush them in a big wave and they will never know what hit them

LOL, no.
Thankfully.

It would have taken out Albany too.

that was just for illustration

Here I thought it could be useful...
What was the corresponding impact on the Atlantic?
Thanks for finding this. I was afraid it was going to be another “maybe-might have-could have-we think-possibly” type article, rather than something based upon actual field data.
There was a SF / fantasy series that was set in the Mediterranean basin during the dry years - The Gandalara Cycle by Randall Garrett and Vicki Ann Heydron IIRC. I remember reading and liking the series when I was younger (though it’s not great fiction by any measure). The last book ends with the flood waters pouring through Gibraltar and the Gandalarans scrambling to get out of the hole.
So what about all those water dwelling dinosaurs whose remains we find all over the place?
