Occupations protohistoriques et médiévales en marge du village actuel de Ruvigny : Ruvigny, Aube "Proche l'Eglise". Document final de synthèse
2018
L’occupation se caractérise tout d’abord par une batterie au moins une soixantaine de silos de la transition entre le premier et le second Âge du Fer avec un bruit de fond Néolithique (mobilier résiduel) et Bronze final (quelques fosses et silos). Certains de ces silos ont livré un important mobilier céramique qui, couplé à des rejets de forges et des objets attestant d’un travail de tissage, pourrait indiquer la présence d’un habitat associé à proximité immédiate. L’activité métallurgique est attestée dès le Hallstatt D3.Si aucune inhumation n’a été retrouvé dans les silos, quelques ossements humains épars ont été prélevé dans quatre d’entre eux. Il faut également noter la présence du dépô…

Landslide susceptibility modelling for extreme rainfall-triggered multiple landslides: a key study from the 2009 event in the Giampilieri Area(Sicily…

Exploring relationships between grid cell size and accuracy for debris-flow susceptibility models: a test in the Giampilieri catchment (Sicily, Italy)
2016
Debris flows are among the most hazardous phenomena in nature, requiring the preparation of suscep- tibility models in order to cope with this severe threat. The aim of this research was to verify whether a grid cell-based susceptibility model was capable of predicting the debris- flow initiation sites in the Giampilieri catchment (10 km2), which was hit by a storm on the 1st October 2009, resulting in more than one thousand landslides. This kind of event is to be considered as recurrent in the area as attested by historical data. Therefore, predictive models have been prepared by using forward stepwise binary logistic regression (BLR), a landslide inventory and a set of geo- environmental …
Regional debris flow susceptibility assessment using HRDEM: Example of the city area of Messina (Sicily, Italy)
2014
Shallow landslide and debris flows are among the most dangerous natural hazards triggered by extreme meteorological events. These phenomena have recently caused catastrophic scenarios in Italy (e.g. in Sarno-Quindici and Giampilieri) and, according to expected changes in the climate pattern, an increasing frequency of these phenomena is expected. The aim of this research is to assess the debris flow susceptibility in the Giampilieri area (Sicily) using a spatially-distributed debris flow runout model based on topographic information. The application of the model starts with the identification of the source areas from which debris flows are propagated on the basis of frictional laws and flow…
Ancient architecture in Provence between the Iron Age and the Imperial era: the pillars of the Château-Bas site in Vernègues
2013
The site of Château-Bas (Vernègues, Bouches-du-Rhône), famous above all for its Augustan Roman temple, has yielded a set of pillars decorated either with writhing snakes or with straight rods. As yet there are no known parallels to such pillars. The discovery of a fragment of a pillar reused in a 1st c. AD structure demonstrates that these carvings are ancient. The architectural study of the fragments and comparison with other sculptural elements from southern Gaul suggest they date approximately to the turn of the millenium. The originality of these pieces should perhaps be sought in the copying and adaptation of Italic architectural features (Attic base, Tuscan capital) to a particular fo…
Exploring relationships between pixel size and accuracy for debris flow susceptibility models: a test in the Giampilieri catchment (Sicily, Italy).
2014
Debris flows are among the most hazardous phenomena in nature, which typically take the form of multiple-occurrence regional landslide events triggered by intense driving inputs such as storms or earthquakes. The main tasks of this study were to verify whether cell-based susceptibility models is capable of predicting debris flow initiations in the Giampilieri catchment (southern Italy) and to explore the relationships between the pixel size of the adopted mapping units in terms of predictive performances of the derived models. The Giampilieri catchment is a small area (10km 2 ) hit by a storm on the 1 st October 2009 which resulted in the triggering of more than one thousand landslides and …
