Study that collects, from a more general perspective, all the information on the problem of sand loss and the disappearance of beaches in the Maresme region. From a more specific level, the study focuses on the port of Masnou and the coastal dynamics correction measures that can be applied there.

The study focuses on floristic diversity and impacts on dune systems along the Catalan coast. Twenty-one dune-restricted plant species were identified as indicators of ecological integrity. A new index was applied to measure species diversity relative to total site biodiversity. Results indicate that dunes with less human activity retain more native species.

This study analyzes the impact of the distribution of coconut (Cocos nucifera L.) on the beaches of the Dominican Republic and its relationship with coastal erosion and the dynamics of beach-dune systems. A total of 31 beach-dune systems were compared using 17 qualitative variables to assess the influence of palm trees planted for agricultural or touristic purposes on beach morphology, anthropic occupation, and dynamics. The results indicate that beaches with palm trees planted for touristic purposes exhibit higher compaction, slumping, and erosion, as well as lower resilience in the beach-dune system. These beaches also have a higher presence of tourist complexes, mechanical cleaning, and removal of vegetal debris, which contributes to the alteration of the beach profile and native vegetation. Palm trees can also act as wave flow accelerators, exacerbating sediment loss and increasing the risk of the palms themselves falling, which entails personal risks. It is concluded that the removal of coconut palms and comprehensive beach restoration, including the recovery of dune fronts and associated vegetation, are necessary actions to improve the stability and dynamics of Dominican coasts. Furthermore, the importance of developing planning and management strategies that promote the conservation and restoration of beach-dune systems in touristic and agricultural areas is suggested.

This study analyzes the historical transformation and current situation of the dune landscape in Catalonia.

Location and characteristics of the geotechnical surveys of the subsoil carried out (boreholes, penetrometers and test pits).

The study analyzes changes in the forest landscape of the Costa Brava over the past century through the comparison of historical and contemporary photographs. The results show a significant increase in forest cover, with the recovery of pine and oak forests, while agricultural areas have declined. This suggests a shift in land use and in the tourist perception of the landscape.

The Map for the Prevention of Geological Risks is a document that represents the geological hazard of the territory at a scale of 1:25,000. It is a multi-hazard map, which offers an overview of the hazards identified in the territory. The territory is zoned, for each hazard considered, into high, medium and low hazard, and is represented according to traffic lights. The symbology used allows the type of phenomenon causing the hazard to be identified, while the phenomena and indicators of this hazard are represented.

Inventory of defence structures built to reduce the risk of avalanches. Single and lineal structures are documented, such as artificial avalanche release systems, road barriers, breakers, deflection structures, retention nets, screens, wind baffles, deflectors, rigid and flexible barriers, retention walls, reforestation and controlled areas.

This study analyzes the historical management of coastal dune fields on the Catalan coast to understand their changes over time.

This article updates the floristic knowledge of the species that colonize the beaches and dunes of the Catalan coast. The study identifies typical species of these habitats, as well as those restricted to dunes. A total of 87 dune systems were sampled, identifying 224 species, of which 87 are considered typical of beach and dune habitats, and 34 are exclusive to these environments. The presence of exotic species reflects human impact on these ecosystems.
