Natural Hazard Risk Management: a Multidisciplinary Approach to Define a Decision Support System for Shallow Rainfall-Induced Landslides

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 infor- mation 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 Engineer- ing 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).
