L’évolution Diachronique Des Intéractions Urbanisation / Cours D’eau. Cas De La Ville De Bejaïa (Littoral Algérien)

Abstract

The diachronic evolution of the urbanization/riverways interactions. The case of the city of Bejaïa (the Algerian Coast). In the Mediterranean city of Bejaïa, the urban phenomenon has had, over the centuries, certain repercussions on the natural spaces, in particular those of the river environments, which are numerous in this city. This work aims to study this phenomenon from two perspectives, namely the geographical and temporal space. Spatial urban interventions in Bejaïa represent the material to be studied; as for time, it is considered the unit of measurement of urban evolution and the changes it causes to rivers. Thanks to a geo-historical method, we will direct our research towards the exposure of the influences exerted by the urban phenomenon on the waterways of the study area, from the creation of the city to present day. The objective of this theoretical presentation is to summarize the transformations of the links between urbanization and the hydrology of the study area.
