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.

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 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.

Report analysing the effects of the early September 2023 DANA in Catalonia (heavy rainfall focused on Terres de l’Ebre and significant swell), based on press, social media, municipal inputs and satellite imagery, including an impacts inventory.
-
Geomechanical study that defines and applies geomechanical stations along the Catalan coast to describe lithologies, discontinuities and strength parameters (q_u), GSI and Hoek–Brown mi, with RMR classification, photo record and sampling; includes GIS inventory and 202 station sheets.
-
Study characterising the intrinsic erodibility of the geological materials of the Catalan coast through lithological, geomorphological and cartographic analysis, including coastline classification, Holocene deposits and bedrock units.
-
This study provides an overview of the last 40 years of use, and in many cases abuse, of natural resources in Catalonia, with proposals for sustainable management.

The publication includes two documents related to the socioeconomic benefits of metropolitan beaches: on the one hand, an evaluation of the economic value of the beaches in the metropolitan area of Barcelona, and on the other, a report on the socioeconomic impact of metropolitan beaches.
-
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.
