Did the Nile River flow to the Gulf of Sirt during the late Miocene?

Satellite imageries coming from Landsat ETM+ and ERS (European Remote Sensing) radar sensors, together with elevation data collected by the Shuttle Radar Topography Mission (SRTM) in addition to recent and older bibliography, led to the hypothesis that, before the Late Messinian drawdown of the Mediterranean Sea, Nile River flowed to the Libyan palaeo-Sirt. The study is still in progress; in this abstract are presented data coming from three areas, that are showing evidences of palaeo-drainage of Tortonian-Late Messinian age, that could be considered sufficient to delineate the path of the Nile River up to the Gulf of Sirt.
