This technical report is an update and expansion of the preliminary studies for the stabilization of the beaches of Gavà and Viladecans, of December 2019. This new document analyzes the entire coastal section that extends from the mouth of the Llobregat river to Ginesta port and the evolution of the shoreline from 1990 to 2020, critical areas and related problems are identified with coastal stability, and action strategies are proposed that can solve the problem that has been identified.

Synthesis of the geology of Catalonia at a scale of 1:50,000 through the cartographic representation of geological units of a lithostratigraphic nature, of the major structural elements (unconformities, faults and folds) and of the types of contact between units.

Analysis of the diversity and complexity of the coastal landscape, resulting from the interaction between natural and human processes.

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.

The Gloria storm affected the Catalan coast between January 19th and 23rd, 2020. The study characterizes the wave climate and the prior morphodynamic conditions, compiles the most notable impacts, and proposes the need for a shift in coastal management towards an ecosystem-based approach.

Geothermal 3D model of the Fossa del Camp, developed as part of the Deep Geothermal energy project (GeoEnergia-GP) by the ICGC. More specifically, this model contains the lithological units, the main geological structures, the geothermal model with the 3D temperature and geothermal potential distribution of several mesozoic aquifers in the Fossa del Camp, the location of the exploration drilling Reus-1 and the topographic surface of the scope of the project.

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 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.

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 study analyzes the floristic composition and vegetation structure in the dune spaces of the Llobregat Delta, highlighting the changes caused by natural and anthropic factors. The impacts of exotic species, especially invasive ones, are also discussed.
