Forecasting rainfall-induced landslides

focus-sake-evidenza We developed GASAKe, Genetic Algorithm-based Self-Adaptive Kernel, a new model to predict the time of occurrence of rainfall induced landslides.GASAKe predicts the time of occurrence of single landslides or groups of similar landslides, both shallow and deep-seated, using a threshold than when exceeded determines the initiation of the landslides. The triggering threshold is defined using historical information on rainfall and ...

Geohazard impact assessment for urban areas

progetto-safety-evidenza- The project is focused on monitoring geohazard-associated ground deformations, a key prevention action specifically addressed to urban areas and critical infrastructures. The project will propose a procedure to produce maps to assess continuously the potential impact of geohazard activity. These maps will provide inputs to support early warning, giving information on the stability of the monitored areas and to evaluate the expected ...

Earthquake-induced landslides

focus-frane-sismoindotte-wasowski-evidenza Landslides and earthquakes are important geological hazards in Italy, where mountains and hills dominate a landscape characterized by the presence of weak geological materials. The geological and morphological settings result in high susceptibility to landslides under seismic conditions. Italy is also one of the most active tectonic regions in Europe; and seismic shaking is known to have caused landslides in Italy.Numerous historical ...

Where we should not expect landslides?

nonsusc_valcmonica_20150726_3D_IN_EVIDENZA-3 Landslide susceptibility is the propensity of a territory to generate landslides.Many methods are available to determine landslide susceptibility, whereas only a few attempts were made to outline areas not likely to generate landslides i.e., non-susceptible landslide areas. This is surprising, because for planning purposes it is just as important (if not more important) to know where landslides are not expected than to know where landslides ...

Joint modeling of landslides and erosion processes

LANDPLANER_Copertina_20150721- Different approaches have been proposed to model landslide and erosion processes separately. Only a few attempts have been made to model landslide and erosion jointly. Some models consider the effects of landslides on sediment yield and transport. In other cases, landslides and erosion processes are components of a landscape evolution model. However, existing models do not describe jointly the triggering mechanisms of landslide and erosion ...

Landslide susceptibility models and maps

LAMPRE leaflet Landslide susceptibility is the likelihood of a landslide occurring in an area, given the local terrain conditions. It is the degree to which an area can be affected by future landslides i.e., an estimate of “where” landslides are more likely to occur.Landslide susceptibility does not consider the temporal occurrence or the magnitude of the expected landslides. In mathematical language, landslide susceptibility can be expressed as the ...

Rheology of geological processes

evidenza-roger Critical and depositional friction angles are characteristic for the deposition of a granular mass; the wrong angle adoption determines the ineffectiveness of a containment basin. The term is used with different meanings and measured by various procedures. The numerical simulation is a useful tool for the hazard assessment, but the definition of friction needed parameters requires insights on their ...

Damaging geo-hydrological events in Calabria from 1990 to 1999

focus-calabria-2-evidenza We published a book entitled “Eventi alluvionali in Calabria nel periodo 1990-1999” (Alluvial events in Calabria from 1990 to 1999)Link to the Book» The volume is the result of a study that lasted more than a year, and was part of long-lasting research effort to investigate historical landslide and flood events in Calabria, which started in the ‘70s of last century.To search the information, we went to the Public Provincial ...

Historical landslides and floods in Calabria

focus-petrucci-evidenza-1 Landslides and floods tend to hit places that by their nature and geographic location are more likely than others to be damaged. Knowing the location of these places, and how they have been affected in the past by landslides and floods, allows to draw damage scenarios for possible future events.For years, we have studied historical landslide and flood events in Calabria. Our investigations have allowed us to reconstruct a unique historical ...

STRESS

evidenza-cariplo-inondazione The STRESS project is intended to design, implement and test a prototype of a Spatial Information Infrastructure (SII) enabling the provision to spatial planners and risk managers of new data and tools to improve hydro-geological susceptibility, hazard and impact assessment as well as to experiment alternative decision making ...
