Sinkholes represent a natural risk that may hit catastrophically without clearly detectible precursors. However, they are often overlooked by people and administrators. Therefore sinkhole monitoring associated early warnings constitute important research topics but, currently, only few papers about prediction can be found. In this paper an experience of warning with GB-InSAR is described. The latter highly precise instrument able to produce displacement maps metric spatial resolution....

Abstract The mode of channel‐bend transformation (i.e. expansion, translation, rotation or a combination thereof) has direct bearing on the dimensions, shape, bedding architecture and connectivity point‐bar sandstone bodies within fluvial meander belt, but is generally difficult to recognize in vertical outcrops. This study demonstrates how bend relative rate channel‐floor aggradation can be deciphered from longitudinal outcrop sections aligned parallel meander‐belt axis, as crucial...

The Upper Valdarno Basin stands out from the Neogene-Quaternary basins of Northern Apennines given its outstanding fossil mammal record, good quality natural and artificial outcrops remarkable chronological control on basin-fill succession. present paper aims to summarize stratigraphic sedimentological studies focused during past decades, integrate them with recent investigations. is located about 35 km SE Florence between Chianti Mountains Pratomagno Ridge. It consists a main asymmetric...

We describe stratigraphic, structural and kinematic data from the sediments of Upper Pliocene Santa Barbara Basin its substratum. The results shed light on relationships between tectonics sedimentation in larger Late Pliocene-Middle Pleistocene Valdarno which is considered a precursor. filling up are made alluvial to deltaic lacustrine deposits,grouped Castelnuovo dei Sabbioni (CSB) Synthem, related Pliocene. This synthem was deposited tectonic depression reasonably delimited East by...

Gravity-induced pyroclastic density currents (PDCs) can be produced by the collapse of volcanic crater rims or due to gravitational instability materials deposited in proximal areas during explosive activity. These types PDCs, which are also known as “glowing avalanches”, have been directly observed, and their deposits widely identified on flanks several volcanoes that fed mafic intermediate magmas. In this research, suitability landslide numerical models for simulating gravity-induced PDCs...

Abstract. A big challenge in terms or landslide risk mitigation is represented by increasing the resiliency of society exposed to risk. Among possible strategies with which reach this goal, there implementation early warning systems. This paper describes a procedure improve activities areas affected high risk, such as those classified critical infrastructures for their central role society. research part project LEWIS (Landslides Early Warning Integrated System): An System Landslide...

Nowadays many developing countries need effective measures to reduce the disaster related risks. Structural interventions are most achieve these aims. Nevertheless, in absence of adequate financial resources different low-cost strategies can be used minimize losses. The purpose this paper is demonstrate that risk reduction gathered building a community coping capacity. In case study, flood and seismic analyses have been carried out using relatively simple technologies, fundamental for...

In this paper a geomorphological map of the Rotolon landslide is presented. This cartographic product was obtained using combination accurate field surveys together with airborne Lidar analysis, aerial photo interpretation and thermographic within GIS. The prepared in order to analyze morphological features therefore improve GB-InSAR data. monitoring device installed on site after detachment debris mass 225,000 m3 4 November 2010. main purpose post-event activities, including...

Abstract Sediment transport and deposition at river-dominated river mouths are controlled by: i) outflow inertia, ii) turbulent bed friction, or iii) buoyancy. In mouth-bar-type deltas, which typically form in shallow-water settings, friction-dominated effluents prevailing, although inertia-dominated ones may develop depending on: bedload the mouth water depth immediately downstream of outlet. This paper deals with lacustrine deltaic sediments deposited a Pliocene, small, protected lake,...

On November 4th 2010, after several days of intense rainfall, a huge mass (about 225000 m3) detached from the debris cover Rotolon landslide, converging within Creek river bed, and evolving into mobile flow that damaged various infrastructures, putting on high risk three villages located along creek banks. After this event National Department Civil Protection (DPC) appointed Earth Sciences Firenze University (DST-UNIFI) to start ground based interferometric radar (GBInSAR) monitoring...

The management of the coastal environment is a complex issue, which needs for appropriate methodologies.Erosional processes and longshore currents present in submerged beach represent serious danger both people human infrastructures.A proper integration between traditional innovative techniques can help characterization environment.Several different multispectral hyperspectral were used to retrieve information about hydro morphodynamic settings Pisa province coast (Tuscany, Italy).Results...

The study of palaeosols, coupled with the classical methods process sedimentology, is increasingly becoming a powerful tool for palaeoenvironmental reconstructions. intrinsic complementarity these two methods, which record effects processes developing over different periods time, allows to improve detail facies analysis. This type approach has actually never been adopted Upper Valdarno Basin, one best-known continental Plio-Pleistocene basins Northern Apennines. aim this paper document...

The greatest disaster threats in Albania are those related to severe earthquakes and large-scale riverine floods. exposure of Albanian population these occurrences is mainly due underdevelopment, poor infrastructures communications, a rapid urban growth range environmental factors. Structural interventions the most effective reduce risks, but they costly. However, absence adequate financial resources, different low-cost strategies can be used offer measures risk prevention local...

At Il Piano (Elba Island, Central Italy) 11 sinkhole events occurred on 9 different points or close to a strategic road connecting Rio Marina the rest of island. In order reduce risk, ground-based interferometric radar has been experimentally installed detect possible precursor deformations ground. this paper we present results test simulating occurrence sinkhole, which highlighted criticalities method, and successful prediction event that could have endangered people travelling along road....

A slope affected by several landslides threatening a motorway in Southern Italy has been monitored through ground-based radar interferometer for early warning purposes. The capability of such instrument to produce near real-time displacement data the whole scenario optimized an application implementing algorithms reduce file size and regulate frequency transmission. Since activities require high reliability fast transferring but are often carried out remote locations where it is not possible...
