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).

Information regarding an avalanche observed recently. Mapped based on direct observation of the event or observation following it. The information is obtained based on the nivometeorological observation network, rescue groups, countryside wardens, mountain guides, and ski and mountain resort personnel. In the event of important episodes and accidents the IGC technicians also gather information. The elements mapped mainly include the extent to which avalanches affect populated areas, roads, ski resorts and people who carry out mountain activities. Data began to be gathered in 1986. It is shown in blue.

: 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.

Methodological report describing models, data and procedures to analyse flooding and erosion along the Catalan coast.

Report describing the background and methodology for analysing erosion and sediment production in Catalan basins, including previous studies and the Iber model.

Report describing the update of the permanent flooding model and viewer based on IPCC AR6 sea level projections, including new layers, methodology and results.

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.

Preliminary analysis of Storm Nelson’s impacts (27/03–01/04/2024) along the Catalan coast: inventory of impacts, beach evolution and infrastructure damage, supported by post-storm aerial imagery and field surveys.

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.
