Predicting Shoreline Change for the Agadir and Taghazout Coasts (Morocco)

Risk Assessment of Marine Flooding along the Agadir and Taghazout Coasts (Moroccan Atlantic)

“…The mapping of TWL SLR in 2100 horizons, for section 1 more specifically in Agadir (Figure 6), shows the probable flooding of almost the entire beach. The water will invade the front part of the series of hotels, especially in the southern part of the bay, which are already experiencing an aggravation of the erosion phenomenon (Aangri et al , 2022), unlike the northern part of the bay, which is experiencing a silting up due to the port facilities, which will reduce the impact of the phenomenon of marine flooding in this area. It is worth mentioning that the seawall in front of the corniche of Agadir plays a primary role in terms of reducing the impact of the storm wave; however, it has weak points.…”

“…The backshore of the study area beach is equipped with tourist and commercial infrastructures ( e.g ., hotels, cornices, restaurants), and is considered as the first seaside tourist destination in Morocco. In terms of hydro-sedimentary forcing in the study area, the tide is semidiurnal with a mean range of about 2.9 m. The tidal range varies between 0.1 and 3.85 m (Aangri et al , 2022; Hakkou et al , 2011), tide-induced currents on the continental shelf on the order of 0.2–0.3 m/s (Charrouf, 1989; Jaidi, 1981), and swells from the north-west are the most common (Figure 2). The coast of the study area is exposed to high-energy waves traveling roughly from the north-west sector, which are generated by a low-pressure system over the north Atlantic Ocean, and are thus strongly seasonally modulated (Aangri et al , 2022; Hakkou et al , 2011).…”

“…Furthermore, this research endeavors to initiate in-depth discussions on optimal strategies for managing this region. It is worth noting that various development activities, particularly in Taghazout, such as the construction of the cornice and real estate projects, have been carried out without prior sedimentary assessments (Aangri et al , 2022). This study serves as a foundational framework that aims to be refined and enhanced as new methodologies emerge and data becomes available.…”

“…The study area (Figure 1) is restricted to the north of Taghazout Village, the Agadir port complex in the center, and the Oued Souss estuary in the south. The beach spans 120 m to 60 m in width, is made up of medium-sized sand (ranging from 200 µm to 370 µm in size), and has a gentle foreshore slope ranging from 0.68° to 1.28° (Aangri et al , 2022).…”

Diachronic Study of the North Atlantic Coast of Morocco between Larache and Moulay Bousselham: A Geometric Approach

“…These errors are combined according to equation ( 1) to obtain an overall estimate of the coastal position error, expressed by the term 'Esp'. 𝐸𝐸𝐸𝐸𝐸𝐸 = √𝐸𝐸𝐸𝐸 2 + 𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸𝐸 2 + 𝐸𝐸𝐸𝐸 2 + 𝐸𝐸𝐸𝐸 2 (1) where: Esp -coastal position error, Ed -digitization error, ERMSE -errors related to image rectification, Ep -pixel error, Evvariations in the position of the oscillation line induced by high tide level.…”
