: 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 work assesses the level and role of management and the morphological status of coastal dunes in Catalonia and Valencia. Ten beach-dune systems were studied to determine how management actions influence their morphological status. Results show two main groups: those without sustainable management, in an advanced erosive state, and those where sustainable management was applied, presenting good conservation status.

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.

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).

The current sanitary crisis caused by the rapid expansion of COVID-19 offered the possibility of giving respite to dune systems and allowing their natural regeneration after the effects of storm Gloria. This storm affected the Levantine and Balearic coasts between January 21 and 23, and when some systems began to recover, intensive coastal management again compromised the integrity of dune systems. The urgency to have the systems "ready" for consumption and exploitation moves away from the concept of sustainable tourism management and does not contribute to climate change adaptation. In this work, et points out some management actions on emerged beaches that have taken place during lockdown and deconfinement. The study focus on three management actions that reveal malpractice, such as leveling and mechanical cleaning, the construction of breakwaters, and the removal of Posidonia oceanica. For this, several case studies representing some of the best-preserved beach-dune systems in Catalonia and the Balearic Islands have been chosen.

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.

The study analyzes the influx and mobility of recreational and sports boats on the beaches and coves of the Baix Empordà coastline, as well as user behavior and the impact on ecosystems.

Information regarding an area exposed to an avalanche. Mapped based on analysis of the terrain and of signs that avalanches leave in their path, mainly, in forests. In Avalanche Zones, avalanches occur frequently and are of different sizes. Avalanche Zones have been systematically mapped throughout the region. They are shown in orange. There are two types of Avalanche Zones: zones where avalanches usually follow the same path, shown in orange, and zones where avalanches usually follow different paths, shown in pale orange.

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.

The Map for the Prevention of Geological Risks is a document that represents the geological hazard of the territory at a scale of 1:25,000. It is a multi-hazard map, which offers an overview of the hazards identified in the territory. The territory is zoned, for each hazard considered, into high, medium and low hazard, and is represented according to traffic lights. The symbology used allows the type of phenomenon causing the hazard to be identified, while the phenomena and indicators of this hazard are represented.
