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.

This article updates the floristic knowledge of the species that colonize the beaches and dunes of the Catalan coast. The study identifies typical species of these habitats, as well as those restricted to dunes. A total of 87 dune systems were sampled, identifying 224 species, of which 87 are considered typical of beach and dune habitats, and 34 are exclusive to these environments. The presence of exotic species reflects human impact on these ecosystems.

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 Geoanthropic Map is a cartographic document with applied geothematic content in which the current state of the physical constitution of the territory is represented, at the appropriate scale for territorial planning, as a result of anthropogenic action on the geological environment and the geological conditions for human activity. It reflects those geological elements and processes that directly affect or may directly affect human activities, together with those human activities or actions that modify the morphological characteristics of the topographic surface or that may directly affect the physical properties and behavior of the natural terrain. The Geoanthropic Map includes elements typical of a geomorphological map, while, in the Anglo-Saxon sense of the term, it makes an inventory of natural geological processes and artificial interventions in the geological environment. It classifies natural processes according to their activity and orders them according to the areas of generation of the materials involved, the transport mechanisms, the areas of deposition and the characteristics and geological properties of the deposits. Similarly, it classifies artificial elements and deposits according to the activities that have generated them, to which they give or have given service. This map also includes geotechnical determinations, such as a map of lithological groups and structural elements, the degree of consolidation, the degree of weathering, the degree of rippability and other geomechanical properties of the materials.

: 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 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 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.

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

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.

Study that collects, from a more general perspective, all the information on the problem of sand loss and the disappearance of beaches in the Maresme region. From a more specific level, the study focuses on the port of Masnou and the coastal dynamics correction measures that can be applied there.
