The study of the multi dates shoreline evolution in the area of Ksar Esghir, located in the northwest of Morocco on Strait of Gibraltar between Tangiers and Ceuta, allowed the appreciation of the following progressive characters: - Ksar Esghir watershed geomorphologic, which provides a mountainous character, allowing the distinction of the three main units: Highest areas, plain areas and coastal areas. - Typically Mediterranean climate, characterized simultaneously by a cold damp winter and hot dry summer, where the weather and marine conditions are dominated by: Dominant West- North west swells which may exhibit Atlantic Ocean origin and East- North east swells may due to local wind seas. - Evolutionary trend of the Ksar Esghir beaches shorelines, between the years 1966 and 2005 (40 years), marked by: an erosion of approximately 65%, an accretion of 25% and coastal stability of around 10% being considered with an almost total absence of stable areas. - Areas occupancy evolution characterized by: an increase in developed areas with an average annual rate which may reach up + 0.28 km

Abstract
The study of the multi dates shoreline evolution in the area of Ksar Esghir, located in the northwest of Morocco on Strait of Gibraltar between Tangiers and Ceuta, allowed the appreciation of the following progressive characters: - Ksar Esghir watershed geomorphologic, which provides a mountainous character, allowing the distinction of the three main units: Highest areas, plain areas and coastal areas. - Typically Mediterranean climate, characterized simultaneously by a cold damp winter and hot dry summer, where the weather and marine conditions are dominated by: Dominant West- North west swells which may exhibit Atlantic Ocean origin and East- North east swells may due to local wind seas. - Evolutionary trend of the Ksar Esghir beaches shorelines, between the years 1966 and 2005 (40 years), marked by: an erosion of approximately 65%, an accretion of 25% and coastal stability of around 10% being considered with an almost total absence of stable areas. - Areas occupancy evolution characterized by: an increase in developed areas with an average annual rate which may reach up + 0.28 km

Abstract: (french)
L’étude de l’évolution multidates de la ligne du rivage de la région de Ksar Esghir, situé au Nord Ouest du Maroc sur le détroit du Gibraltar entre Tanger et Sebta, a permis l’appréciation des caractères évolutifs suivants : - Une géomorphologique du bassin versant de Ksar Esghir, de caractère montagneux, permettant la distinction de trois grandes unités, avec : Des zones hautes, des zones de plaine et des zones côtières. - Un climat typiquement méditerranéen, caractérisé par un hiver frais et humide et un été chaud et sec, où les conditions météo-marines sont dominées par : Des houles dominantes Ouest à Nord ouest, d’origine atlantique et des houles Est à Nord est, dues à des mers de vent local. - Une tendance évolutive des traits de côte des plages de Ksar Esghir, entre 1966 et 2005 (40 ans), marquée par : Une érosion d’environ 65%, une accrétion d’environ 25% et une stabilité de 10 % des espaces côtiers considérés, avec une absence quasi-totale des zones stable. - Une évolution de l’occupation des espaces caractérisée par : Une augmentation des espaces aménagés avec un taux moyen annuel de + 0,28 Km² / an et une réduction des espaces non aménagés avec un taux moyen annuel de - 0,27 Km² / an.
