Abstract
Coastal regions are among the most vulnerable to the impacts of climate change, with increasingthreats from shoreline erosion, coastal flooding, and inundation. The Skikda coastline, locatedin northeastern Algeria, is particularly susceptible to these hazards due to its geographicalfeatures, low-lying areas, and proximity to river mouths. In this study we want to analyze thevulnerability of the Skikda coastline by focusing on the dynamics of shoreline erosion, coastalflooding, and inundation, using a combination of field data, hydrodynamic modeling, and riskevaluation techniques. The research analyzes the behavior of waves and currents in the area,incorporating both natural and human-induced factors that influence coastal processes.Hydrodynamic models, including the MIKE21 simulation tool, were used to evaluate the effectof various storm scenarios, while hydraulic modeling with the HEC-RAS system providedinsights intotheextentofpotentialflooding in critical zones. The findings reveal significantregional differences, with the eastern part of the coastline showing a higher levelofvulnerability to erosion and flooding compared to the more stable western regions. The studyemphasizes the growing threat posed by rising sea levels and extreme weather events,highlighting the urgent need for sustainable coastal management and adaptive strategies. Bymapping high-risk zonesandunderstanding the driving forces behind coastal dynamics, thisresearch offers valuable information for decision-makers to develop effective mitigation andadaptation measures to protect both the environment and local communities.
