Natural disaster or man-made, why was Libya so vulnerable to floods?

The process of retrieving the bodies washing up on Derna’s shores continues, as the death toll carries on increasing.

According to the Libyan Red Crescent, more than 11,300 are now confirmed to have died after Storm Daniel hit the eastern Libyan city on Sunday and Monday, leading to the failure of two dams, which burst and unleashed torrents of water through a dry riverbed and onto the city.
