Where did waters part for Moses? Not where you think

An illustration based on new research shows how wind could have moved and split waters from two ancient basins.

The parting of the waters described in the book of Exodus that enabled Moses and the Israelites to escape the pharaoh's army is possible, computer simulations run by researchers at the National Center for Atmospheric Research and the University of Colorado at Boulder show.

To test the theory that the biblical account may have depicted actual events, the researchers studied maps of the region, archaeological records and satellite measurements to find a topographical feature where such an event might have been possible. They settled on an area south of the Mediterranean Sea where some oceanographers say a branch of the Nile River drained into what was called the Lake of Tanis, a coastal lagoon 3,000 years ago.

The computer model shows a 63 mph east wind blowing across the area and its 6-feet-deep waters for 12 hours. In the scenario, the wind pushed back the waters into both the lake and the channel of the river, exposing a mud flat 2 to 2.5 miles long and 3 miles wide for four hours. As the winds died down, the waters quickly flowed back in and in theory would have drowned anyone on the mud flat.

“The simulations match fairly closely with the account in Exodus,” said Carl Drews of NCAR, the lead author of the study published in the online journal PLoS ONE. (Read the full study)

“The parting of the waters can be understood through fluid dynamics. The wind moves the water in a way that’s in accordance with physical laws, creating a safe passage with water on two sides and then abruptly allowing the water to rush back in.”

Parting the waters, Part 2: Carl Drews on wind setdown research
The biblical account of Exodus has Moses and his followers trapped by the pharaoh forces against a body of water, which has been translated to both the Red Sea and the Sea of Reeds. In the account, a strong wind comes up after night falls and parts the waters behind the Israelites. Moses leads them into the breach but when the pharaoh army pursues them at daybreak, the gap disappears and the army is lost.

Previous research has focused on areas of the Red Sea near the modern-day Suez Canal where the biblical miracle may have been possible. The NCAR/CU team said their research shows those scenarios unlikely. They ran a series of 14 computer simulations to pinpoint the area where the parting of the waters was most likely.

“People have always been fascinated by this Exodus story, wondering if it comes from historical facts,” Drews says. “What this study shows is that the description of the waters parting indeed has a basis in physical laws."

Drews conducted the Exodus research as part of a larger project on how winds can affect water depths.

    Good day! I know this is kind of off topic but I was wondering if you knew where I could get a captcha plugin for my comment form? I'm using the same blog platform as yours and I'm having difficulty finding one? Thanks a lot!

    I read this book where aliens landed in the US. Will there be a serious study on that? I mean, it was written in a book probably influenced by the aliens, so it must be true.

    Only in America would this be done and called science.

    @Darrell - If you look around, I think you'll find that the Peace, Love, and Understanding part is a fairy tale also.

    @Alexander – Yeah, computer simulations of hydrodynamics based on archaeological data is total pseudoscience.

    @darrell yes bible storties but as for the flood if they had a flood there they would have thought that the whole world did too. most thought that their world was the only one

    @ Darrell re:"Trust me on this..." I DO trust you Darrell. Unquestionably. You are the guru of all things. I am writing a sequel to the Bible and it will begin with the Book of Darrell, because apparently we should trust you.

    was this study done to appease the thumpers?

    @ Joe – Jews as well as Christians and Muslims are right once again!
    Quran corroborates the event's happening!

    I'm in total agreement, Joe. Forget what the crazies say. If they can prove it can be done scientifically, then God didn't do it, if they can't prove it, then God didn't do it and it's pseudoscience. It doesn't matter. It happened. And really, who cares, what anybody really thinks about this?

    If you discount the explanation that God did it, you probably ought to also discount the idea that there actually were any Jews yet.

    If you're not taking the early bible as at least mostly true, then the ancestors of the Jews were still calling themselves Caananites and living the same place as their Jewish descendants did later.

    @Sal, copying isn't really corroborating :-P

    So i guess Moses was a great physicist,.. if he knew so many hundreds of years ago the exact minute to lead the isrealites out of captivity,.. and it took science this long to figure it out,.. what a shame, God is good
