How to define rainfall thresholds automatically

focus-definire-soglie-pluviometriche-evidenza The empirical rainfall thresholds while representing a useful approachused to forecast landslide occurrence in wide areas, are affected by several uncertainties related to the rainfall and the landslide information accuracy, the reconstruction of the rainfall events responsible for the failure, and the method to calculate the thresholds. Definition of the rainfall conditions responsible for landslides is a crucial issue and may contribute to ...

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 ...

Moscardo Torrent – rainfall data

prodotti-dati-archivio-Torrente_Moscardo_pluviometro-evidenza This dataset consists of rainfall data recorded in the Moscardo Torrent (Carnic Alps, northeastern Italy). The Moscardo Torrent was instrumented for debris-flow monitoring by CNR IRPI (Torino office) in 1989; the research was then continued in collaboration with the Padova office. Since 2010 the monitoring activities are carried on in collaboration with the University of Udine (Dept. of Agricultural and Environmental ...

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 ...

Rainfall thresholds for the possible initiation of rainfall-induced landslides in Apulia

DPCPuglia_soil_slips- In Italy rainfall are among the main causes of trigger of shallow landslides, that yearly cause fatalities, damage, and severe economic losses. Identification of the amount of rainfall needed to trigger landslides, and the forecasting of rainfall-induced landslides, are of interest for the scientific community, as well as for the whole ...

Time-Space prediction of high impact landslides under changing precipitation regimes

In Italy a significant increase of landslide frequency and intensity in the last decades has been occurred, whose impact must be evaluated with respect to the convergence in possible negative effects of both rainfall regime changes and of urban development as well as land use changes. Italy, due to its geomorphological and urbanization characters, represents today large areas where landslide risk is at the highest ...

Prediction of rainfall-induced landslides and associated risk in Italy

SogliePluviometriche_Figura1_20150109- In Italy, slope failures occur every year, claiming lives, causing economic disruption, and producing different environmental problems. In Italy, intense or prolonged rainfall is the primary trigger of landslides. Predicting rainfall-induced slope failures is a challenging task of both scientific and societal interest. The forecast of single or multiple landslides triggered by rainfall in wide areas relies primarily on empirical rainfall ...
