Abstract

International audience; The Northern Mediterranean region is the place of many mass movements triggered by climatic events that affect populations and infrastructures every year. These events are largely linked to intense rainfall events that affect the region during the autumn-spring period. They are the cause of catastrophic floods and hundreds of shallow landslides (less than 10000m3). The rain/slip relationship is observed and studied with great interest, the authors easily agreeing on the fundamental role of the "water" variable in triggering gravity instabilities. Indeed, the fluid content of the geological formations determines their geomechanical behavior (increase of the pore water pressure and total mass of the formations) and thus conditions the stability of these formations. In the context of the European INTERREG ALCOTRA AD-VITAM project, particular attention has been focused on the dynamic of sub-surface groundwater and its use in stability calculation models. The relationship between precipitation/sub-surface groundwater/shallow deformation is poorly documented for the long term observation and it is through the analysis of 18 piezometers located in the northern Mediterranean region (France and Italy) representative of sub-surface groundwater as well as meteorological data that we propose an analysis of this relationship. All these piezometers are located in geological layers composed of silt, sand, clay or/and marl highly subject to shallow landslides and alteration processes, an aggravating factor in slope stability. The observed data show very seasonal evolutions of the various piezometric measurements, both in terms of dynamics and periods of ground water level variations. Cross-correlation analyses show a good correlation between precipitation and groundwater dynamics for most piezometer/rainfall gauge pairs and a rapid interaction (max 2 days) between these two variables. We also observe a strong correlation between rainfall and groundwater level with a simple hydrological reservoir model (GARDENIA). The analyses carried out show the essential role of precipitation in the dynamics of sub-surface aquifers. As part of the AD-VITAM Project, these observations will allow calibrating slope stability models where the ground water level observations, which are essential, are not always available or with insufficient time period of acquisition.

Abstract

International audience; The regrouping area, where Hannibal is thought to have reformed his army after forging a path through a massive rockfall in the Cottian Alps, has been reshaped by a blanket of sediment deposited from debris flows following heavy rain in spring, 2008. Analysis of precipitation data for the period mid-May to mid-June, 2008, shows that 722 mm of rain fell at 2150 m, falling off to half that amount at 3325 m on the flanks of Mon Viso. Following exhaustive analysis of environmental factors connected with the invasion of Italy at the start of the Second Punic War (218 bc), identification of the regrouping area for the Carthaginian Army centred on the presence of an ancient stone wall system which possibly dates from Hannibalic times. Lichen cover, lichen diameters, weathering characteristics, degree to which boulders had sunk into the resident soil, and presence of ancient hearths all combined to make this area a choice locale for reconstructive geoarchaeology. Large scale mass wasting off a prominent bedrock bar adjacent to the wall system in the Upper Po River Valley resulted in burial of most of the prominent wall structures which will complicate any exploration geoarchaeology attempts in future.

Abstract

Background: The temporal pattern of effects of summertime ozone (O 3 ) in total, cardiovascular and respiratory mortality were investigated in 21 European cities participating in the APHEA-2 (Air Pollution and Health: a European Approach) project, which is fundamental in determining the importance of the effect in terms of life loss. Methods: Data from each city were analysed separately using distributed lag models with up to 21 lags. City-specific air pollution estimates were regressed on city-specific covariates to obtain overall estimates and to explore sources of possible heterogeneity. Results: Stronger effects on respiratory mortality that extend to a period of 2 weeks were found. A 10 μg/m 3 increase in O 3 was associated with a 0.36% (95% CI −0.21% to 0.94%) increase in respiratory deaths for lag 0 and with 3.35% (95% CI 1.90% to 4.83%) for lags 0–20. Significant adverse health effects were found of summer O 3 (June–August) on total and cardiovascular mortality that persist up to a week, but are counterbalanced by negative effects thereafter. Conclusions: The results indicate that studies on acute health effects of O 3 using single-day exposures may have overestimated the effects on total and cardiovascular mortality, but underestimated the effects on respiratory mortality.

Abstract

Northern Italy is frequently affected by severe precipitation conditions often inducing flood events with associated loss of properties, damages and casualties. The capability of correctly forecast these events, strongly required for an efficient support to civil protection actions, is still nowadays a challenge. This difficulty is also related with the complex structure of the precipitation field in the Alpine area and, more generally, over the Italian territory. Recently a new generation of non-hydrostatic meteorological models, suitable to be used at very high spatial resolution, has been developed. In this paper the performance of the non-hydrostatic Lokal Modell developed by the COSMO Consortium, is analysed with regard to a couple of intense precipitation events occurred in the Piemonte region in Northern Italy. These events were selected among the reference cases of the Hydroptimet/INTERREG IIIB project. LM run at the operational resolution of 7km provides a good forecast of the general rain structure, with an unsatisfactory representation of the precipitation distribution across the mountain ranges. It is shown that the inclusion of the new prognostic equations for cloud ice, rain and snow produces a remarkable improvement, reducing the precipitation in the upwind side and extending the intense rainfall area to the downwind side. The unrealistic maxima are decreased towards observed values. The use of very high horizontal resolution (2.8 km) improves the general shape of the precipitation field in the flat area of the Piemonte region but, keeping active the moist convection scheme, sparse and more intense rainfall peaks are produced. When convective precipitation is not parametrised but explicitly represented by the model, this negative effect is removed.
