“…The area has fairly regular steep slopes (around 40 • ) consisting of layered unsaturated air-fall pyroclastic soils in primary deposition overlying fractured limestone. In situ investigations and monitoring of suction and rainfall are available (for details see Damiano and Olivares, 2010;Damiano et al, 2012) as well as mechanical and hydraulic properties of the soils (for details about experimental programmes and geotechnical models see Olivares andPicarelli, 2001, 2003;Olivares and Damiano, 2007;Greco and Guida, 2008;Greco et al, 2010).…”

Abstract. This paper proposes a Multidisciplinary Decision Support System (MDSS) as an approach to manage rainfallinduced shallow landslides of the flow type (flowslides) in pyroclastic deposits. We stress the need to combine information from the fields of meteorology, geology, hydrology, geotechnics and economics to support the agencies engaged in land monitoring and management. The MDSS consists of a "simulation chain" to link rainfall to effects in terms of infiltration, slope stability and vulnerability. This "simulation chain" was developed at the Euro-Mediterranean Centre for Climate Change (CMCC) (meteorological aspects), at the Geotechnical Laboratory of the Second University of Naples (hydrological and geotechnical aspects) and at the Department of Economics of the University of Naples "Federico II" (economic aspects). The results obtained from the application of this simulation chain in the Cervinara area during eleven years of research allowed in-depth analysis of the mechanisms underlying a flowslide in pyroclastic soil.

“…The infiltration process was numerically simulated assuming the hypothesis of homogeneous deposit and applying either the average daily rainfall intensity observed during rainy days (pluviometric measurements), or the evaporation flux during dry days (estimated from Cervinara suction measurements [13,20]), as top soil surface boundary condition. For the lateral and bottom boundary conditions, free flow was assumed.…”

Abstract:The paper presents a Multidisciplinary Decision Support System (MDSS) to analyse rainfall-induced shallow flowslides on steep slopes covered by pyroclastic deposits. This system proposes an approach to provide technical information to the agencies responsible for civil protection and land management about the link between forecasted rainfall and the effects in terms of infiltration, slope stability, vulnerability and mitigation policy. This approach was developed at the Euro-Mediterranean Centre for Climate Change (CMCC) (meteorological aspects), at the Department of Civil Engineering of the Second University of Naples (hydrological and geotechnical aspects) and at the Department of Economics of the University of Naples "Federico II" (socio-economic aspects). It has been designed as a multidisciplinary approach which simultaneously addresses the issues from different points of view, providing a comparison and integration of the different skills. The potentiality of this approach is presented for the case of the flowslide of Cervinara (Southern Italy).

“…In the last years, several authors identified different soil hydro-mechanical behaviors leading to shallow landslides triggering through the application of monitoring tools [2][3][4]. Moreover, monitoring data revealed very useful to be implemented in different kinds of physically-based methods for the assessment of slope stability at site-specific and local scales [5][6].…”

The Impact of Hydrological Parameters on Modelling Slope Safety Factor Towards Shallow Landslides: A Case Study from Oltrepò Pavese

Abstract. Hydrological monitoring of slope susceptible to shallow landslides allows for identifying the triggering conditions of shallow failures and implementing slope stability analysis at site-specific scale. In this work, a case study of a long-term hydrological monitoring in a slope susceptible to shallow landslides of Oltrepò Pavese (Northern Italy) is presented. The triggering mechanism develops in wet seasons (winter and spring) due to the uprise of a perched water table at about 1 m from ground surface, in consequence of the most intense rainfalls (about > 60 mm in 48 h). Unstable conditions (safety factor < 1.0) are correctly modeled on the basis of both water content and pore water pressure, with a better prediction considering hysteresis effects. Safety factor on the basis of water content can correctly assess the triggering conditions for unsaturated and completely saturated soils. It is possible estimating shallow landslides triggering caused by positive pore water pressures only considering this parameter.
