Saving Alexandria: Egypt’s ancient metropolis faces new threats from the sea
Tens of thousands of concrete wave-breaking devices have been installed in strategic locations, including in front of Qaitbay Citadel. The face of Alexandria is changing and it needs to, according to experts.
Sea level rise is happening at a faster rate here than in many other parts of the world. For a low-lying city like Alexandria, it is a threatening scenario, which promises to reshape coastlines, contribute to coastal erosion and lead to more flooding and saltwater intrusion.
Beyond the slow onset rise of the sea, which certain models show could result in city inundation within decades, perhaps of more immediate alarm is the increase in extreme events, like heavy rain and storms. So too, is Egypt warming also twice as quickly as the rest of the planet, due to climate change.
“What Alexandra really suffers from in recent years is the occurrence of extreme events. In the last few years we have lived with prolonged summers with very high temperatures, more than the normal we used to live with,” said Tarek El-Geziry, professor of physical oceanography at the National Institute of Oceanography and Fisheries.
“And on the other hand, we have shorter winter periods, but with low temperatures and severe conditions. Add to this is the issue of the expected sea level rise.”
