: 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.

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.

Extension report of the rapid response works for the late October and early November 2023 sea storms of late October and early November 2023.

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.

Methodological report setting theoretical bases, parameters and mapping guidance to incorporate active and recent coastal processes into the 1:25,000 geo-anthropic map, describing morphology, morphodynamics, driving agents and proposed indicators and symbology.

This study analyzes the structure and dynamics of the coastal juniper forest of Punta de la Creueta in Tarragona, comparing it with juniper forests of the island of Mallorca.

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 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.

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.

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.
