The researchers added: “After a high-stand level concomitant with the African Humid Period, our results show that Giza’s waterscapes responded to a gradual insolation [solar radiation] -driven aridification of East Africa.”
The Nile began to drop, they explained, not long after the reign of King Tutankhamun, which ended in the year 1323 BC.
Evidence for the aridification of Egypt at this time has also been found in the bones and teeth of mummified individuals.
The lowest Nile levels, the team noted, were recorded at the end of the Dynastic Period, which concluded with the death of Cleopatra in 30 BC.
The full findings of the study were published in the journal Proceedings of the National Academy of Sciences.
