This study evaluates the geomorphological state of 12 beach-dune systems over time, classifying them into four stages according to their degree of degradation: 1- systems in a natural state (two beaches), 2- highly altered or disappeared dune systems (three beaches), 3- dune systems in recovery process (five beaches), and 4- stabilized dune systems (two beaches).

Based on the "Preliminary Studies for the stabilization of the beaches of Sant Adrià de Besòs, Badalona and Montgat", of March 2021, this document proposes a series of stabilization measures for the beaches of Badalona and Montgat.

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.

The study analyzes the spatiotemporal evolution of the dune systems of Alt and Baix Empordà based on geomorphological and management variables applied in 16 periods between 1956 and 2016.

This study assesses the changes in coastal dune landscapes in Catalonia, based on photographic, cartographic, and documentary sources between 1890 and 1960, comparing them with the current status of dunes.

This study aims to develop high-resolution digital elevation models to quantify changes in sediment retention and dune height both pre and post construction of the fences.

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.

The dune system of La Pletera has been studied using unmanned aerial vehicles (UAVs) to assess the effects of sand traps and revegetation. The volumetric data obtained from UAV RGB sensors was compared with data from the previous Lidar flight.

Analysis of the diversity and complexity of the coastal landscape, resulting from the interaction between natural and human processes.

This study analyzes the sediment loss associated with the removal of Syringodium filiforme berms from 10 beaches in the Dominican Republic. The results show that approximately 63.8% of the removed volume corresponds to interspersed sediment. This type of management has a continuous morphological impact, affecting the stability of the system's sediment balance.
