Since the most remote times in the history of mankind, man has been trying to tame hydro power by building dams across streams. This trend is one of the oldest activities of the humanity. The increase in the world population and the legitimate expectation of an improvement in the standard of living have increased the demand for water. To counter this challenge, an intensification of building dams across the five continents was committed during the twentieth century. The world dam park has currently more than 60,000 large dams.
During the last twenty years, Algeria has built a large number of dams to reach 75 dams in 2017, corresponding to a surface water mobilization rate of about 80%.
Despite this progress in the field of water mobilization, two major factors will increase the stakes: on the one hand, the climate change, making water resources more irregular thus favoring longer periods of drought, increased floods and sedimentation early of reservoirs; and on the other hand a growth in the demand for water. These two challenges must be addressed by adopting a strategy that allows an additional mobilization of water resources and the rehabilitation of the existing dams to increase their security and conserve their storage capacity. This conference aims to bring together people with varied profiles (researchers, engineers, experts …) in order to exchange scientific knowledge and experience. This will help define the conservation prospects of the existing dams and new technologies for the construction of new dams based on the economic aspect and the protection of the environment.
