Integrated assessment of geo-hydrological instability phenomena in the Apulia region, interpretative models and definition of rainfall thresholds for landslide triggering

project-GeoPuglia-2018-evidenza The Apulia region is affected by multiple types of geo-hydrological instability processes such as sinkholes, flash floods and landslides.Landsliding mainly affects the north-western sector of the Region (bordering with Apennine chain) and the sea rocky cliffs.The sub-Appennine Daunia portion of the Region is exposed to landslide risk due to hydro-geological setup of the soil/rock deposits, the poor mechanical properties of the ...

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 ...

ALMOND-F, an ALarm and MONitoring system for Debris-Flows

The ALMOND-F equipment installed on the left bank of the Gadria torrent. The structure also includes a raingauge, a solar panel and the box containing the data logger ALMOND-F is an innovative unit for the microseismic detection of debris flows using a network of geophones.The microseismic detection of debris flows is more complex than other types of monitoring. Use of the geophones requires: (1) the selection of the level of amplification of the signal, which depends on the distance from the stream; (2) the selection of the sampling frequency of the seismic signal, which must be sufficiently high; (3) ...

Flood forecasting and flood risk assessment

evidenza-floris The project is focused on flood forecasting and hydraulic risk, i.e. the assessment of the effects of flooding in flood-prone areas also involving the vulnerability assessment of the hydraulic structures (dams, leaves, bridges, ...

SARF Sardegna

evidenza-sarf-sardegna In Italy, landslides are triggered by intense and/or prolonged rainfall. The spatial and temporal forecast of multiple landslides triggered by rainfall in wide areas relies primarily on empirical rainfall thresholds. It is widely believed that the thresholds are influenced by the local topographic (morphological), lithological, soil, and climatic settings. For this reason, it is necessary to define local rainfall thresholds. Reliable local ...

Landslide Multi-Hazard Risk Assessment, Preparedness and Early Warning in South Asia Integrating Meteorology, Landscape and Society

evidenza-landslip In India, as in many other areas in Asia and in the world, landslides are abundant and frequent, and they represent a serious hazard to the local population. The aim of LANDSLIP is to develop tools, including operational systems, to contribute to reducing impacts of hydrologically related landslide multi-hazards and to building resilience to landslides in vulnerable and hazard-prone areas of ...

Dikes and Debris Flows Monitoring by Novel Optical Fiber Sensors

project-DOMINIO-fronte-evidenza With more than 5 million people affected, more than 1000 killed, and with estimated total damages exceeding 4.5 billion Euros just in Europe and during the last decade, floods are among the most disruptive natural events threatening our Society. Due to increase in extreme weather events and rapid socio-economic developments in vulnerable locations, the risks connected to floods in general are growing rapidly, and the awareness of these risks ...

Threedimensional Displacement Analysis

prodotti-servizi-3da-evidenza The 3DA software is a new procedure that allows retrieving in near-real-time 3D surface deformation models starting from data acquired via robotized total stations or others system that acquire the surface displacements. The measurements are first pre-processed and then implemented on 3D maps that include vector arrows representative of the intensities and of the real directions of motion in a given system of coordinates. The 3D surface ...

Forecasting system for geo-hydrological risk

Regional early warning index maps (ordinary in green, attention in yellow, pre-alarm in orange and alarm in red). Real time evaluation of the rainfall and soil moisture conditions over the analysis grid point, and the combination with the available vulnerability and susceptibility information for the definition of the dynamic risk ...
