Contribution of two-dimensional modelling in assessing marine submersion risks: A study of the Saidia-Cap de l'Eau and Al Hoceima Bay coastlines

The onset of climate change is exacerbating sea level rise and intensifying storms, leading to increased coastal degradation, notably in the form of coastal erosion. This represents a global phenomenon, and the coastlines of Al Hoceima Province and Saidia-Cap de l'Eau in the Mediterranean are no exceptions. The primary objectives of this study include the following: 1) to utilise Geographic Information Systems (ArcGIS) for simulating marine submersion phenomena along the Al Hoceima Bay and Saidia-Cap de l'Eau coastlines, 2) to employ two-dimensional modelling using Iber 2D software for a more nuanced understanding of marine submersion, and 3) to map the marine submersion risk in these areas. Our findings indicate that the areas most at risk from marine submersion are the low-lying sandy beaches in both study areas.
