The study analyses the evolution of the coastline and the hydrodynamic behaviour of the beach in the municipality of Gavà and the possibility of implementing a stabilization solution with a geotube similar to that used in Sète (France). It also collects environmental information and the characterization of the habitats, marine communities and sediments in this environment. Finally, it proposes a roadmap to improve and expand knowledge of the problems detected and propose appropriate solutions.

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.

Dades LiDAR de les platges de l'àrea metropolitana de Barcelona (excepte el Port de Barcelona). Han estat obtingudes el novembre de 2017 amb una densitat de 4 punts/m². Les dades han passat un procés de classificació automàtica per distingir el terreny de la resta d'elements, i han estat tallades per municipis segons un tall irregular.

Limits of the areas of natural interest defined in Decree 328/1992, which approves the Plan of areas of natural interest (PEIN), and any subsequent modifications that may have occurred. This base includes spaces at a scale of 1:50 000 and, in some cases, 1:5 000. The PEIN establishes a network of spaces representative of the rich landscape and biodiversity of the territory of Catalonia, from high mountains to coastal plains, and from Euro-Siberian forests to semi-desert wastelands or marine spaces. The PEIN is the higher level planning instrument that structures the system of protected areas of Catalonia and integrates this system within the whole territory, as it is a sectorial territorial plan framed within the Territorial Plan of Catalonia (1995). Subsequent to its approval, specific modifications to the rules and limits have been approved by decree, as well as extensions or additions of new spaces.

Boundaries of the natural spaces of Catalonia that form part of the European Natura 2000 network. Natura 2000 is a European ecological network of areas that may have been proposed as special protection areas for birds (ZEPA) in accordance with the Directive 2009/147/CEE, also known as the Birds Directive, and/or as Special Areas of Conservation (ZEC) in accordance with Directive 92/43/CEE, also known as the Habitats Directive. In the first instance, the Government of Catalonia approves the proposal for sites of Community importance (LIC) for the Natura 2000 network of the areas of the Alpine and Mediterranean biogeographical regions. Subsequently, the European Commission adopts the conformity of this proposal and finally the Government of Catalonia declares the LICs as ZECs.
