Abstract:
Coastline of Bejaia extended on a hundred kilometers, a touristic area that has got
many beautiful beaches. The latter, was converted to an anthropogenic pressures (upstream
construction of Tichy_half's dam and to the implantation of the industrial zone of downstream
cevital group engendering a degradation of this beautiful place (the disappearance of some
beaches as Sidi Ali Lebhar and Tassifth).
Our goal consisted on better understanding the operation of this Coastal fringe
including the terrestrial part which includes the watershed of Soumam wadi being at the base
of alimentary source by its contributions firstly. Secondly, by the interpretation of different
traces of the coastal lineages of this zone (Over a span of twenty-eight years) from the high
resolution aerial photographs collected during our internship in the INCT and by the
evolution of its underwater relief.
This work informs us that this coastal is characterized by a morphology more or less
regular parallel to the coast of a strong erosion and a weak accretion. In addition, its sediments
are various and its maximum to the fines.
This erosion is a major issue which echoes negatively on the socio-economic and
tourist activities of the region.
Keywords: aerial photographs, coastlines, watershed, modelization, coastline kinematics, bay
