Five Quaternary units, dating from the Middle Pleistocene to the Historic period, are identified in the study area. They are the results of the activities of various morphodynamic agents. Diffuse waters were responsible for shaping two generations of glacis from Middle to Late Acheulean (Middle to Late Pleistocene). Torrential and diffluent waters, for their part, generated the interlocking of two generations of alluvial fans, attributed to the Mousterian and the Capsian (Upper Pleistocene to Holocene). In addition, the longitudinal water inputs from the mountain system are responsible for the establishment of a single generation of terrace attributed to the Capsian (Holocene to Historical) which fits into all of the quaternary forms described.

The study of the forms and deposits of quaternaries allowed us to draw a synthetic section. This shows the position as well as the chrono-stratigraphic succession of different units by representing the morphological evolution of the studied area.
