wadi

The results showed the tools were likely to have been used approximately 84 thousand years ago and then abandoned on the banks of the wadis and subsequently buried over time.

The desert riverbed, or wadi, had already subsided back to a trickle.

A series of bridges had crossed the wadi, connecting the port area with the western side of the city.

An academic published a paper in 2022 said that repeated flooding threatened the dams built in a wadi, a usually dry riverbed, above the city and urged immediate maintenance.

"If a huge flood happens the result will be catastrophic for the people of the wadi and the city," the paper said.
