[Termes IGN] système expertRésumé : (Auteur) In this paper, two simple GIS-based methodologies have been used to assess the landslide susceptibility in a basin located in Southern Italy. The methodologies at issue, based on the spatial distribution of landslides and/or of causal factors, are bivariate statistics-based and expert-based, respectively. The spatial distribution of both the landslides and the causal factors has been investigated by integrating pre-existing and original data, which have been processed using ArcView GIS 3.2 software. The obtained results, consisting of landslide susceptibility maps have been compared and discussed. The bivariate statistics-based method has provided the most satisfying results. On the contrary, the expert-based method has provided a classification of the study area in terms of landslide susceptibility which does not completely fit with the surveyed spatial distribution of the landslides.

[Termes IGN] vulnérabilitéRésumé : (Auteur) The response of environment to ashfall was evaluated aiming at defining the vulnerability in the areas surrounding Mt. Etna volcano, Sicily. The two utilized scenarios assume different thickness of ashfall, over distances comparable with those covered by deposits from realistic eruptions that occurred recently on the volcano. The fall episodes are considered instantaneous or with a duration of 90 days. These models are in agreement with the actual and recent activity of the volcano. The evaluation of vulnerability was performed by a GIS-based method, accordingly with the different themes that constitute the Corine Land Cover inventory of the study area and discovering the potentially damaged elements following the two hypothesized scenarios.

[Termes IGN] stabilitéRésumé : (Auteur) Dealing with the evaluation of the risk connected to the formation of landslide dams at regional scale, it is important to estimate the volume of the depleted material that can reach the riverbed. This information, combined with other elements (river dimensions, valley width, landslide velocity, etc.) allows making predictions on the possibility of river blockage. One of the problems of this approach is the lack of data concerning the shape and position of the sliding surface; this does not permit us to estimate the volume of the landslide material. The IFFI (Inventario dei Fenomeni Franosi in Italia, i.e. Landslide Inventory in Italy) project furnishes information, at different levels of precision, on nearly totality of the landslides existing in Italy. The first level of the IFFI (compiled for all slides) does not contain information on the depth of the sliding surface but contains data regarding the type and the activity of the slope movement. Along with this information the IFFI project also furnishes vector maps containing the boundary of each landslide and the main sliding direction. This paper describes the implementation of an algorithm aimed to define, with an adequate approximation, the 3D geometry of the sliding surface of rotational slides for which, on the basis of geologic maps available at regional scale, some geotechnical parameters can be known or estimated. The work also required the creation of a computer code useful for the 3D analysis of slope stability (3D safety factor) using the simplified Janbu method. All computer code has been created on a GNU-Linux OS and using shell scripting, based on GRASS GIS and R statistical software.

[Termes IGN] stratigraphieRésumé : (Auteur) Mainstream techniques for the construction of 3D geological models frequently rely on high-density subsurface datasets, such as 3D seismic surveys or dense 2D seismic grids. In settings where the available geological and/or geophysical data are relatively sparse, the construction of a consistent 3D structural framework is seldom straightforward and is strongly dependent on the optimization of the use of surface data. To deal with this challenge, workflows for constructing 3D models from sparse surface data have been proposed by multiple authors. This paper presents three automated techniques which optimize the use of data and enhance the time-efficiency of 3D model construction: 3D geological contact analysis, 3D dip-domain construction, and 3D isopach measurement and construction.

[Termes IGN] WebSIGRésumé : (Auteur) A web site was designed to disseminate new information on historical landslides and floods in Umbria, central Italy. The historical information was compiled through a thorough review of existing catalogues of historical landslide and flood events, supplemented by an extensive search of local historical archives and chronicles, for the period before 1900. The new catalogue lists 1983 landslide events in the period from 1139 to 2001, and 1956 flood events in the period from 860 to 2001. In the considered period, in Umbria there were at least 1,531 sites affected one or more times by landslides, and at least 1,071 sites affected one or more times by inundations. The seasonal distribution of landslides and inundations was found different before and after 1900, most probably because of incompleteness of the historical record prior to 1900. WebGIS technology was used to disseminate the geographical and thematic information on historical landslides and floods in Umbria. The GIS-based web site is aimed at a diversified audience of experts and private citizens seeking information on geo-hydrological hazards in Umbria.

[Termes IGN] utilisation du solRésumé : (Auteur) A rock fall occurs when a fragment of rock is detached from a cliff and travels down-slope at high speed. Rock falls are a constant hazard in mountainous regions and pose a significant threat to the population. In this paper, a comparison of software designed to model rock falls is presented. The computer codes selected for the experiment are STONE and RocFall®. STONE is a research code for the 3-dimensional simulation of rock falls. RocFall® is commercial software widely used for the 2-dimensional simulation of rock falls along user defined topographic profiles. The two computer programs require similar input and provide comparable outputs, allowing for a quantitative evaluation of their modelling results. To compare the software, the Monte Salta rock fall, in northern Italy, was selected. Specific tests were designed to compare the ability of the software to predict the maximum travel distance of the falling boulders, and the distance from the ground of the computed rock fall trajectories. Results indicate that the two rock fall modelling codes provide similar—but not identical—results. In general, STONE computes higher and longer rock fall trajectories than RocFall®, and allows identifying a larger area as potentially affected by falling boulders.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) This paper presents the initial results of a common methodology for the evaluation of damage produced by a flood. A model has been developed for flood damage estimation based on a geographic information system (GIS). It could be used by land administration bodies and insurance companies to manage flood-related damage data. The model simulates flood scenarios and evaluates expected economic losses from the impact of floodwaters on exposed elements, through the application of a computational model elaborated by GIS. During the development of the model, the Boesio Stream, a small watercourse flowing into Lake Maggiore (Lombardy, northern Italy) which was recently affected by a flash flood, was used as case study to test and calibrate the methodology. The method could be used either as a forecasting tool to define event scenarios, utilizing data from events simulated with a hydraulic model, or for real-time damage assessment after a disaster. The approach is suitable to large-area damage assessment and could be appropriate for land use planning, civil protection and risk mitigation.
