“…Williams and Micallef 2009). In the Catalan coast, Ariza et al (2008) identified the dominance of recreationally oriented beach management where the beach is mainly considered as a product to be offered to users. They also found that about 50% of the municipalities had suffered erosion-related problems affecting existing beach infrastructures.…”

A methodology to analyse the influence of erosion on beach functions at a regional scale is presented. The method considers erosion hazards at different timescales and assesses consequences by evaluating impacts on recreation and protection functions. To provide useful information to decision makers for managing these functions, hazard and consequences are integrated at the municipal level within a risk matrix. This methodology is applied at the Maresme, a 45-km sandy coast situated northward of Barcelona, which supports a strong urban and infrastructure development as well as an intensive beach recreational use. Obtained results indicate differentiated erosion implications along the region, depending on the management target considered. Thus, southern municipalities are more prone to erosion affecting the protection function of the beach and leisure use by the local population, whereas erosion will have a greater effect on foreign tourism in the northern municipalities. These results highlight the necessity to employ an articulated erosion risk assessment focusing on specific targets depending on the site in question. This methodology can help coastal managers to adopt tailored measures to manage erosion impacts towards specific goals, in a more efficient and sustainable manner.

“…Despite the socioeconomic importance of sandy beaches in Mediterranean waters (Alarcón Urbistondo, 2002;Ariza et al, 2008), most studies on littoral and shallow benthos composition and dynamics have focused on rocky substrates, very often related to Marine Protected Areas (e.g. Díaz et al, 2005;Linares et al, 2005;Follesa et al, 2007), whereas soft substrates, and particularly sandy beaches, have been somewhat neglected (e.g.…”

SUMMARY:The sublittoral megabenthic assemblages of a northwestern Mediterranean coarse sandy beach exploited for the bivalve Callista chione were studied. The spatial and bathymetric variability of its distinctive faunal assemblages was characterised by quantitative sampling performed with a clam dredge. The taxa studied were Mollusca Bivalvia and Gastropoda, Crustacea Decapoda, Echinodermata and Pisces, which accounted for over 99% of the total biomass. Three welldifferentiated species assemblages were identified: (1) assemblage MSS (Medium Sand Shallow) in medium sand (D50=0.37 mm) and shallow waters (mean depth =6.5 m), (2) assemblage CSS (Coarse Sand Shallow) in coarse sand (D50=0.62 mm) in shallow waters (mean depth =6.7 m), and (3) assemblage CSD (Coarse Sand Deep) in coarse sand (D50=0.64 mm) in deeper waters (mean depth =16.2 m). Assemblage MSS was characterised by the codominance of the bivalves Mactra stultorum and Acanthocardia tuberculata. C. chione was dominant in both density and biomass in assemblages CSS and CSD. The occurrence of the crab Thia scutellata also characterised assemblage CSS, whereas the occurrence of the sea urchin Echinocardium mediterraneum characterised assemblage CSD. A depth breaking point of around 10 m determined the discontinuity between assemblages CSS and CSD, which was related to the closure depth of the beaches in the study area. Species richness was highest in the coarse sand communities; however, Shannon-Wiener diversity and Pielou equitability indexes were higher in the shallow fine sand community.Keywords: sublittoral, megabenthos, faunal assemblages, sediment characteristics, biodiversity, NW Mediterranean, coarse sand, Bivalvia, Crustacea. RESUMEN: Comunidades faunísticas de un hábitat sublitoral de arena gruesa en el Mediterráneo Noroccidental. -Se han estudiado las comunidades megabentónicas sublitorales de playas de arena gruesa afectadas por la pesquería del bivalvo Callista chione en el Mediterráneo noroccidental (Maresme). Se ha caracterizado la variabilidad espacial y batimétrica de las comunidades faunísticas presentes mediante un muestreo cuantitativo utilizando un rastrillo de bivalvos. Los taxones estudiados fueron Mollusca Bivalvia y Gastropoda, Crustacea Decapoda, Echinodermata y Pisces, los cuales representaron más del 99% de la biomasa total. Se identificaron tres comunidades bien diferenciadas: (1) comunidad MSS en arenas medias (D50=0.37 mm) y poco profundas (profundidad media =6.5 m), (2) comunidad CSS en arena gruesa (D50=0.62 mm) en aguas someras (6.7 m), y (3) comunidad CSD en arenas gruesas (D50=0.64 mm) en aguas más profundas (16.2 m). La comunidad MSS se caracterizó por la codominancia de los bivalvos Mactra stultorum y Acanthocardia tuberculata. C. chione dominó en densidad y biomasa en las comunidades CSS y CSD. La presencia del braquiuro Thia scutellata también caracterizó la comunidad CSS, mientras que la presencia del erizo Echinocardium mediterraneum caracterizó la comunidad CSD. Se detectó una discontinuidad entre las comunidades CSS...

Human intervention on the coast has been intense, due to the source of wealth that the coastal areas represent, especially in the form of tourism, which has resulted in a rapid erosion of its beaches. This paper discusses the current state of beach management in the various competent public administrations on the Costa Blanca (SE Spanish-Mediterranean), in relation to urban development and regression on the waterfront. To this end, an analysis has been carried out of the responses to a survey of those responsible for managing each of the 19 coastal municipalities of the Alicante coast, covering 244 km of coastline, 91 beaches and their personnel. Also, an investigation has been conducted as to whether this management's aim is to protect the coastline and maintain the flora and fauna or just to manage recreation as the main economic activity is tourism. The analysis shows that the beach is simply regarded as a product or service offered to the user thereof. However, local authorities have not detected problems, possibly for two reasons: they do not have sufficient knowledge and this is understandable, given their lack of responsibilities in this area. This causes many beaches to have a high occupancy rate and there is a shift of users towards natural beaches. The study gives us information about the complex administrative process in the coastal system that often proves ineffective on this narrow strip of land.
