    The boreholes database is an inventory of subsurface data in Catalonia through the collection of available geological and geotechnical survey information. The surveys are classified into three groups: surveys, penetrometers and trial pits.

    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.

    The GeoBase of soils of Catalonia v1.0 is a database intended to store information on soils caught in the field and that necessary for generate soil maps of the territory of Catalonia at different scales, such as the Soil Map 1: 25,000 of Catalonia (MSC25M), or other maps that have been previously prepared (eg at scales 1: 25,000 and 1: 250,000). Contains information on soil profiles with varying levels of detail captured in the field (observations and pits), the composition on horizons, some of its physical and chemical characteristics as well as different types of soils that appear in an area, its spatial distribution.

    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 technical report is an update and expansion of the preliminary studies for the stabilization of the beaches of Gavà and Viladecans, of December 2019. This new document analyzes the entire coastal section that extends from the mouth of the Llobregat river to Ginesta port and the evolution of the shoreline from 1990 to 2020, critical areas and related problems are identified with coastal stability, and action strategies are proposed that can solve the problem that has been identified.

    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.

    The study analyzes the floristic composition and vegetation structure in the dune spaces of the Llobregat Delta, highlighting the changes caused by natural and anthropic factors. The impacts of exotic species, especially invasive ones, are also discussed.

    The study analyzes the evolution of the beaches of Sant Adrià de Besòs, Badalona and Montgat during the last decades to be able to characterize the problems encountered there, identify the most critical points and define initial proposals to solve the problem of regression they suffer.

    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.
