IV.2. Assessment of coastal vulnerability to erosion
A ranking of coastal vulnerability to erosion has been conducted on a scale of 5. In this study we
chose the ranking of coastal erosion vulnerability of (McLaughling et al. 2010). Include NonVulnerable Areas (1), Low-Vulnerable Areas (2), Moderately Vulnerable Areas (3), Vulnerable
Areas (4) Highly vulnerable Areas (5). Five vulnerability classes account for the entire coast of
Skikda, as shown in (figure 35).
According to the mapS (figure 35, 36, 37, 38) there is more highly vulnerable areas on the east
coast, especially in Djendel Saadi Mohamed, Benazouz and El Marsa in addition to Kerkera in the
west coast. All remaining municipalities are generally considered to be in the moderate class.
The differences of vulnerability classes are described as follows:
1. Non-Vulnerable Areas presented in green: They represent coastal regions that are relatively
resilient to erosion and coastal hazards. These areas have natural protective features such as
stable beaches and dunes that mitigate erosion risks, non-vulnerable areas are less likely to
experience significant coastal erosion.
2. Low-Vulnerable Areas presented in light green: Low-vulnerable areas exhibit a slightly
higher degree of vulnerability compared to non-vulnerable areas. While erosion and coastal
hazards are not as severe as in more vulnerable zones, there might be occasional localized
erosion or vulnerability during extreme weather events, the overall risk level is still relatively
low, and the impacts are generally manageable.
3. Moderately Vulnerable Areas presented in yellow: Moderately Vulnerable Areas may
experience more frequent erosion events, higher erosion rates. Coastal management
strategies and mitigation measures are often required to reduce the risks associated with
erosion and coastal hazards. The majority of the coastal zone of Skikda is moseratly
vunerable.
4. Vulnerable Areas presented in orange: Vulnerable areas are characterized by a high degree
of susceptibility to coastal erosion and hazards. They face significant erosion rates. They are
characterized by densely populated areas, critical infrastructure, making them more
vulnerable to the impacts of erosion.
5. Highly Vulnerable areas presented in red: experience significant erosion rates, resulting in
the loss of coastal land over a relatively short period. The erosion and degradation of these
habitats not only impact their biodiversity and ecological functions but can also result in the
