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.

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.

Information regarding an avalanche observed recently. Mapped based on direct observation of the event or observation following it. The information is obtained based on the nivometeorological observation network, rescue groups, countryside wardens, mountain guides, and ski and mountain resort personnel. In the event of important episodes and accidents the IGC technicians also gather information. The elements mapped mainly include the extent to which avalanches affect populated areas, roads, ski resorts and people who carry out mountain activities. Data began to be gathered in 1986. It is shown in blue.

Classification of soil according to its agrological capacity (ability to sustainably produce the most common crops in an area), in one of the 8 classes established by the Generalitat de Catalunya (Government of Catalonia).

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.

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).

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 study analyzes the historical transformation and current situation of the dune landscape in Catalonia.

This study analyzes the changes in the dune landscape of Catalonia as a result of urban and tourism pressure and describes the main dune systems that still persist, highlighting their causes of degradation.

This study analyzes the historical management of coastal dune fields on the Catalan coast to understand their changes over time.
