Strangely enough, the ancient Egyptians "for some reason after building it, they let it fall into disrepair rather quickly. By (the) time Tutankhamun was buried, flooding events had become a problem again," Ghonim said.
"That was bad for most tombs, but good for Tutankhamun since, at least according to one theory, flooding events effectively sealed the tomb and made it inaccessible to later tomb robbers."
Today flood control is still a problem in the Valley of the Kings, and scientists are looking at ways to protect the tombs.
"There have been many studies recommending what to do, but the need to keep the valley open and the costs involved remain a problem. There's also the need to develop a consensus on such an important thing," Ghonim said.
More discoveries and challenges Many more finds will be detailed in scientific publications in the future, including the excavation of huts used by the workers who built the tombs and the documentation of graffiti left throughout the valley's history.
