The contribution of GIS in the quantification of the evolution of Skikda's coastline between 1960 and 2002 and the impact of developments

Abstract

The coastline is considered as a place of great physical and socioeconomic complexity. The concentration and competition from human activities have caused damage to the environment. Coastal erosion is a natural phenomenon of the morphological evolution of coastlines. However, in recent decades this phenomenon has become a very important coastal risk that threatens different types of constructions (harbor, tourist facilities, urban area…). Therefore, the analysis and monitoring of the evolution of the coastline and research on the impact of developments on the coastal environment allow defining a better management and coastal planning. This article presents the dynamic evolution of the coastline using geomatics tools. The diachronic analysis of the evolution of Skikda's coastline shows a strong morphological variability manifested by a net decline of the coastline, seriously threatening the stability of the infrastructures.
