Land movement, also mass movement or mass wasting, indicates the downslope movement surface materials, such as soil, rock, or mud. Land movements are influenced by geological and environmental phenomena, as instance they can be triggered by earthquakes and landslides. The phenomenon can occur suddenly or very slowly, depending on the characteristics of the area and the hazard event. Apart from earthquakes, they typically occur along hillsides and mountains and can naturally happen or being a consequence of human actions. Land movement can impact on the landscape and the archaeological heritage of an area, by damaging and destroying standing and buried structures, as well as archaeological stratigraphy. Damages potentially increased in case of abandonment and in the absence of an effective strategy of risk analysis and monitoring of the area.RESEARCH aims at developing an EO data processing chain based on the use of medium/high-resolution Synthetic Aperture Radar (SAR) data, putting together existing and newly developed modules: differential interferograms generation, deformation map calculation through specific algorithms, surface velocity map generation as input to the structure stability risk model. Differential SAR interferometry (D-InSAR) and Persistent Scatterer Interferometry (PSI) methods are used to assess the stability of the ground and identify ground motion caused by processes as subsidence and landslides at and near archaeological sites. A reliable model for evaluating land movement risk will be designed and developed using the output data of the data processing chain combined with archaeological vulnerability data coming from archaeological field campaigns and remote sensing. Software and risk model development will provide the opportunity for secondments among partners.
Soil erosion is a natural phenomenon of soil loss manly due to water runoff and wind.
Coastal erosion, agricultural activities, urban sprawl, uncontrolled vegetation growth are only some of the factors provoking land use change.
RESEARCH project aims at the creation of a Thematic Platform including back-end and front-end (Web Portal) and external interfaces.
