A terrestrial laser scanner (TLS) allows the generation of a detailed model landslide surface. In this way, when two or more georeferenced models obtained by multi‐temporal scans are available, displacement field can be computed. Nevertheless, such computation is relatively complex task because recognition correspondences among required. The Iterative Closest Point (ICP) algorithm alignment 3D objects having common part iterative shape matching. new method for automatic calculation presented...
Abstract The design of remediation works for the mitigation and prevention associated risk is needed where these geological hazards affect anthropized areas. Remedial measures landslides commonly include slope reshaping, plumbing, drainage, retaining structures internal reinforcement, while debris flow control consist in open or closed structures. effectiveness remedial implemented must be assessed by evaluating reduction over time. choice most appropriate cost-effective intervention...
Abstract. In this paper, we examine variations in climate characteristics near the area of Cortina d'Ampezzo (Dolomites, Eastern Italian Alps), with particular reference to possible implications for debris-flow occurrence. The study is prone release response summer high-intensity short-duration rainfalls and, therefore, it utmost importance investigate potential increase triggering rainfall events. critical threshold agreed be a crucial factor debris-flows. Data from monitoring system,...
Landslides threaten more than before the urbanized areas and are a worldwide growing problem for already affected communities local authorities committed to landslide risk management mitigation. For this reason, it is essential analyze dynamics environmental conditioning factors. Various techniques instruments exist investigation monitoring. Out of these, Multi-temporal Synthetic Aperture Radar Interferometry (MT-InSAR) have been widely used in last decades. Their capabilities enhanced by...
Abstract Direct measurements of the hydrological conditions for occurrence debris flows and flow behaviour are outmost importance developing effective prevention techniques. An automated remotely controlled monitoring system was installed in Acquabona Creek Dolomites, Italian Eastern Alps, where occur every year. Its present configuration consists three on‐site stations, located debris‐flow initiation area, lower channel retention basin. The is equipped with sensors measuring rainfall,...
Abstract. On 9 October 1963 a catastrophic landslide suddenly occurred on the southern slope of Vaiont dam reservoir. A mass approximately 270 million m3 collapsed into reservoir generating wave that overtopped and hit town Longarone other villages nearby. Several investigations interpretations collapse have been carried out during last 45 years, however, comprehensive explanation both triggering dynamics phenomenon has yet to be provided. In order re-evaluate currently existing information...
Abstract. The definition of hydrological alert systems for rainfall-induced landslides is strongly related to a deep knowledge the geological and geomorphological features territory. Climatic conditions, spatial temporal evolution phenomena characterization landslide triggering, together with propagation mechanisms, are key elements be considered. Critical steps development consist identification variable triggering minimum rainfall threshold occurrence. In this paper we report results from...
Abstract. In this paper, spatial data available in the Italian portals was used to evaluate landslide susceptibility of Euganean Hills Regional Park, located SW Padua (northeastern Italy). Quality, applicability and possible analysis scales online were investigated. After a brief overview on WebGIS around world, their contents tools for natural risk analyses, study area carried out using simple probabilistic approach that compared distribution influencing factors. The input factors depended...
Abstract. The main aim of this paper is to test economic benefits landslide prevention measures vs. post-event emergency actions. To end, detailed- and large-scale analyses were performed in a training area located the northeastern Italian pre-Alps that was hit by an exceptional rainfall event occurred November 2010. On detailed scale, reactivated after 2010 investigated. Numerical modeling demonstrated remedial works carried out – water-removal intervention such as drainage trench could...
Terrestrial laser scanner (TLS) and interferometric synthetic aperture radar (InSAR) allow the acquisition of data on an observed surface with high spatial sampling rate. The provided by TLS observation a landslide ground can be used to generate very detailed digital model this surface, multitemporal observations or continuous InSAR provide reliable displacement map. In order acquire useful information about analogies, differences, capabilities, as well limitations these techniques, joint...
Abstract Deep-seated gravitational slope deformations (DSGSDs) are fairly common phenomena in the Eastern Italian Alps. The Celentino DSGSDs (Trentino–Alto Adige Region, Peio Valley) extends over an area of approximately 5 km 2 between 2400 and 1050 m a.s.l. (metres above sea level), involving metamorphic rocks. A set parallel ridge-top trenches antislope scarps present upper part a length km. shear surface is inferred at 80–100 depth, involved volume estimated to be 3.5×10 8 –4.0×10 3 ....
The paper illustrates the procedures for computing probability of failure occurrence that represents potential a slope can undergo due to both spatial variability structural and geomechanical aspects joint sets existing boundary conditions. presented approach global probabilistic assessment rock slopes stability conditions is based on analysis mass, uncertainty in properties, probabilities certain values seismic forces rainfall intensities. Finally, recurrence computed taking into account...
Abstract. Monitoring of debris flows aimed to the assessment their physical parameters is very important both for theoretical and practical purposes. Peak discharge total volume are crucial designing effective countermeasures in many populated mountain areas where losses lives property damage could be avoided. This study quantifies relationship between flow depth, acoustic amplitude induced ground vibrations front velocity experimental catchment Acquabona, Eastern Dolomites, Italy. The...
