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.

Orthophoto (mosaic of rectified aerial images) of the coastal strip (total or partial), with a resolution generally between 10 and 15 cm above the ground, generated from photogrammetric flights.

Based on the "Preliminary Studies for the stabilization of the beaches of Sant Adrià de Besòs, Badalona and Montgat", of March 2021, this document proposes a series of stabilization measures for the beaches of Badalona and Montgat.

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 study analyzes the evolution of the beaches of Sant Adrià de Besòs, Badalona and Montgat during the last decades to be able to characterize the problems encountered there, identify the most critical points and define initial proposals to solve the problem of regression they suffer.

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.
