Models of geo-hydrological processes

project-modelli-processi-geo-idrologici-evidenza-2 The area of interest specifically refers to the study of the following themes: extreme hydrological events and their interaction with slopes and watercourses; soil water erosion; debris flows; slope stability; triggering instability mechanisms; evolution of slope movements; monitoring systems for gravitational movements for the purpose of alerting for the mitigation of geo-hydrological risk. The activities proposed in the module are therefore ...

Geological investigations in the catchment of the Rio Kortol

project-sauris-evidenza Past debris flows in the Rio Kortol catchment arise concerns for the safety of the village of Sauris di Sotto, and urge new studies for the assessment of hazard and the choice of risk mitigation ...

Characterization, modelling and monitoring

project-geo-c3m-evidenza The project concerns the mitigation of natural hazards (mainly the effects on the territory and the anthropic environment caused by rains, earthquakes, volcanism, and Radon gas). The geological characterization is essential to frame the contexts and the expected phenomena. Numerical modeling and monitoring allow to predict the spatio-temporal evolution of the phenomena, and therefore to evaluate the risk for mitigation ...

Kinematics of slow-moving active landslides

focus-Modellazione num_sezioni Portalet-evidenza We experiment the application of 3D numerical modelling techniques for the analysis of the kinematics of slow-moving active landslides. The activity assesses the hazards posed by slow-moving landslides, determines the factors controlling the slope processes, investigates the potential evolution of the active slopes, and helps selecting appropriate slope mitigation strategies.We exploit modern numerical modelling techniques based on finite ...

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 ...

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 ...

Landslides investigation and mitigation at Passo della Morte (UD)

evidenza-Pdm-Hillshade5fenomeni-20160909 L’area del "Passo della Morte" (UD) è interessata da una situazione di grave dissesto a causa della presenza di più movimenti franosi. Questi sono caratterizzati da elevata pericolosità in relazione alle caratteristiche intrinseche dei fenomeni  (volumetrie e velocità di spostamento), alla morfologia del versante ed alla geologia dell'area. La loro presenza mette a rischio la rete stradale che collega la Carnia con il Cadore e l’asta ...

How much Mar Piccolo peculiarities are due to groundwater outflow

5 concettualizzazione-evidenza- The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment.In primarily karstic environments, infiltration is greater than runoff; in the karstic coastal Apulian aquifers, the groundwater discharge to the sea is more than two-fold greater than the surface discharge, notwithstanding the high discharges by wells. In such ...
