“…19), suggests that this section is of strong agitation, which is not favorable for the accumulation of sands. Similar results were obtained by Frihy and Lofty (1997), and Idrissi et al (2004) in their analyses along the northern Sinai coast of Egypt and on the coastal zone of Casablanca, Morocco.…”

“…It is hypothesized that significant wave heights can reach 7-9 m during severe storms (Benmohammadi et al, 2007). The tide is mesodiurnal (Idrissi et al, 2004) with a tidal range of 2.2 m on average, which can vary from 0.9 to 3.5 m during neap and spring tides, respectively. Tide-induced currents on the continental shelf are of the order of 0.2-0.3 m/s (Idrissi et al, 2004;Hakkou et al, 2011) with generally northward and southward currents during flow and ebb, respectively.…”

“…However, continuous nearshore wave measurements are strongly lacking along this section of the Moroccan coastline and numerous knowledge gaps remain on wave climate. The tide is of meso semi-diurnal type (Idrissi et al 2004) with a tidal range of 2.2 m on average which can vary from 0.9 to 3.5 m during neap and spring tide, respectively. Tide-induced currents on the continental shelf are on the order of 0.2-0.3 m/s (Jaidi 1981;Charrouf 1989) with generally, northward and southward currents during flow and ebb, respectively.…”

Wave climate and morphosedimentary characteristics of the Kenitra–Bouknadel sandy coast, Morocco

et al. 2011

The Bouknadel-Kenitra 20-km sandy coastline is of strong interest from the perspectives of beach amenity, tourism and erosion issues. This section of the Moroccan coastline has only received little attention in the literature so far and morphosedimentary characteristics as well as wave climate are poorly understood. The present paper provides the first extensive description of both wave climate and alongshore variability in the morphosedimentary behavior of these wave-dominated beaches, combined with accurate topographic surveys, 9-year long global wave model output time series and subsequently driven empirical longshore drift formula and shoreline change measurements from aerial photographs. Results show that the coast is mainly exposed to high-energy low steepness NW waves (mostly during the October-March period) generated in the North Atlantic by eastward traveling low pressure systems. Given the shoreline orientation, northward and southward longshore drift components generated by this wave regime nearly balance. In contrast, the lower-energy higher steepness N-NW wave regime (April-September period) contributes to an overall quantity of sand being transported southward similar to the yearly averaged net longshore drift. Beaches are mostly of the double-barred intermediate type. The southern beaches exhibit persistent rhythmic sandbars and rather steep beachface while the northern beaches are close to the dissipative state despite all the beaches are exposed to the same wave regimes. Beach states predicted using the Dean's number roughly match these observations. While previous studies elsewhere had shown that inherited geological factors may overwhelm contemporary dynamics in the determination of beach states, here differences are attributed to coastal protection works that appear to be important additional determinants of beach morphology.
