: 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 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.

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

Diagnosis identifying and assessing archives and documentary collections (local, supra-local and general) for the historical study of floods, marine storms, erosion and other hazards on the Catalan coast, including criteria, methodology and research options with estimated archive work units (UTA).

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.
