This study assesses the changes in coastal dune landscapes in Catalonia, based on photographic, cartographic, and documentary sources between 1890 and 1960, comparing them with the current status of dunes.

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.

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.

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.

The central element is the 1:25,000 geological map; the rest are called peripheral elements. The peripheral elements are: the legend of the cartographic units, the conventional signs, the stratigraphic columns, the geological sections, the stratigraphic relationship diagram, the geological diagram and the complementary diagrams. The geological map shows the distribution of different types of rocks that emerge on the surface of the earth and their relative arrangement. It allows us to deduce much of the arrangement of rocks in the subsoil and to learn about the geological history of a region. It is a two-dimensional graphic representation that allows us to make extrapolations in three dimensions or, even, four if time is considered, depending on the level of reading that is made. It is formed by a set of cartographic units limited by contacts and by symbols that represent other geological elements: surface dip, folding structures, subsoil information (isopachs or isobaths of the Quaternary), slope of recent deposits, morphological indications, landslides and other recent processes, deposits, etc. It also includes symbols of various references (geological sections, drillings, names of major geological structures, etc.).

3D model of Port del Comte aquifers, developed as part of the assessment of underground water resources available in Catalonia. More specifically, this model contains the lithological-hydrogeological units, the main geological structures, the topographic surface of the project area, the location of the main karst springs and the saturated rock volumes of the water reservoirs associated with each of the springs

3D model of geological surfaces that contains the main stratigraphic surfaces and geological structures of Catalonia, the location of the main exploration drillings and the topographic and bathymetric surface of the model area.

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

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 map contains a detailed representation of the relief, depth, seabed type and marine habitats identified on the coast of Catalonia. The area surveyed was the entire Catalan coast up to 50 m depth. The Marine Habitats Map brings together the following data sets: Marine habitats (EUNIS classification level 3 and 4); Complementary marine habitats (EUNIS classification level 5); Seabed type; Coastal strip elevation model; and Bathymetry.
