The consequences of this situation reveal as fast and emergency rescue excavations that in some cases certainly this haste greatly will reduce the quality of archaeological studies.

From scientific and technical perspective and according to directors of dam excavation projects experience, generally believe that fast and emergency excavation it is not only and surest way to preserve and protect of ancient sites; why, given the little time and lack of adequate funding for dam archaeological projects, of course, excavations excavate only a small parts of the archaeological sites.

Using the boat for going to the sites for excavation, as well as other serious problems in this regard should be add to emergency excavation projects problems...
