Integrated environmental and socio-economic assessment of Flood Risk in a GIS context in the Vipacco Basin’

Abstract

KULTURisk is an European project that aims to evaluate the benefit of risk prevention of water-related natural hazards (Balbi et al.,2012). In particular a Team that work at the Department of Economics of Cà Foscari has developed an integrated assessment methodology to estimate flood risk in a spatially explicit fashion. It is called SERRA methodology and comprises three tiers of analysis: 1)RRA (Regional Risk assessment which provides a physical/ environmental risk assessment; 2)the Social assessment aims at considering the benefits of the human dimension of vulnerability; 3)the Economic assessment which provides an economic evaluation of costs and benefits of different prevention measures This methodology should be a good guideline for its application to different case studies. In particular the case study that interest my work is about risk assessment in Vipacco river sub-catchment (at the border between Italy and Slovenia); Vipacco is an affluent of Isonzo, a river that flows into Mar Adriatico in the Golfo di Trieste. It is presented a spatial implementation of valuation algorithms in a GIS context.
