Scientists in the US studying ancient maps of the Nile Delta region pinpointed where the crossing may have occurred, just south of the Mediterranean Sea.
Here, according to some experts, an ancient branch of the Nile flowed into a coastal lagoon then known as the Lake of Tanis.
Analysis of archaeological records, satellite measurements and maps allowed the researchers to estimate the water flow and depth at the site 3,000 years ago.
An ocean computer model was then used to simulate the impact of a strong overnight wind on the six-foot-deep waters.
The scientists found that an east wind of 63 mph blowing for 12 hours would have driven the shallow waters back, both into the lake and the river channel.
For a period of four hours, this would have created a land bridge about two miles long and three miles wide.
