For several thousand years the water level of the Mediterranean has remained constant, but by the year 2.025 it is estimated that it will rise between 13 and 55 cm. Before a century the rise can be of a meter. The melting of polar ice and the expansion of heat from ocean waters will be two causes of this fact.

Already in Catalonia the delta of the Ebro is going back. The same occurs in the deltas of the rivers Rhône or Po. In addition, the problems of Venice increase pollution and abandonment and the regulated works projected have the key to the future of this beautiful city (See Elhuyar). Science and Technology (number 13).

However, Alexandria of Egypo has the darkest future. Alexandria has 3.5 million inhabitants and is only one meter above the water level. In this case, in addition, we must add the damage caused by the Asuan dam. The mud, sand and other materials formerly transported by the Nile cannot overcome the dam and accumulate in it.

For this reason, the delta of the Nile River does not collect the heap of existing materials and cannot restore the material that takes away the sea. The rise of the water level and the delay of the Nile delta make the future of Alexandria like its famous library, the disaster.
