: Information regarding an avalanche observed in the past. Mapped based on a survey of inhabitants of the area where the phenomenon took place. The boundaries shown are based on the explanations given by the witnesses consulted. Information is usually taken from Avalanche Zones close to inhabited areas where avalanches have historically interfered with human activity. For this reason the majority of the information is found around these zones. They are shown in purple. Cartography often maps only the avalanche arrival zone, as the descriptions usually refer to their extent and the damage caused.

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.

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.

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 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 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.

Synthesis of the hydrogeological macrounits into which the territory can be divided, called hydrogeological areas, and classification of the formations of the Geological Map of Catalonia 1:250,000 according to their lithological characteristics, type of porosity and consolidation.

Technical report describing the execution of boreholes and CPTU tests in six coastal plains of Catalonia to characterize Holocene deposits and determine their geotechnical properties.

The study examines human influence on the evolution of beach-dune systems in the Balearic Islands, focusing on afforestation with Pinus halepensis. Historically, actions have been taken to stabilize these areas, significantly impacting the morphology and dynamics of the systems. Through a historical review and analysis of 31 such systems, it is evident that the presence of Pinus halepensis is largely associated with human interventions, significantly affecting vegetation structure and biodiversity conservation.

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.
