WMS Service (Web Map Service) National Soil Erosion Inventory (2002-2019). Potential for mass movements

The Web Map Service called the National Inventory of Soil Erosion (2002-2019) Potential for mass movements, allows the visualization and consultation of the evolution of erosive phenomena, with the ultimate aim of delimiting as accurately as possible the priority areas of action in the fight against erosion, as well as defining and assessing the actions to be carried out, within the plans and programs whose preparation is also attributed by Royal Decree 500/2020, of 28 April, which develops the basic organizational structure of the Ministry for the Ecological Transition and the Demographic Challenge, and modifies Royal Decree 139/2020, of 28 January, which establishes the basic organizational structure of the ministerial departments. The objective is the identification and qualitative classification of areas of potential risk to present mass movements and their typology. Mass movements are mechanisms of erosion, transport and deposition that are produced by the gravitational instability of the terrain. Its interrelation with other erosion mechanisms is very intense, especially in mountain areas, where together with torrential hydrodynamics make up the main denudative process of the slopes. This aspect is patented in the typological and quantitative consideration of mass movements in most torrent classifications. Outside the torrential basins, its contribution to the erosive dynamics is also important, being often precursors and / or consequences of acarcavaciones and erosions laminares and in waterways. In this module we tried to determine the areas potentially susceptible to this type of phenomena, based on the basic characteristics of the territory that define this risk, mainly lithology, slope and rainfall. Active movements identified through bibliographical collection, as well as seismic risk, were also taken into account. Consequently, based on the overlapping of the coverages corresponding to the different factors involved, the potentiality mapping was developed. In the areas with the greatest potential, the predominant typology of the possible movements was also determined, generating also the corresponding cartography.
