摘要

According to climate modellers, probability, frequency, duration, intensity (seriousness) of extreme weather events (extremerntemperatures and rainfall) are increasing and will be more frequent in future. The former will lead to higher surface runoff and floodrnevents while the latter will cause landslides phenomena and a break of roads network. The impact of such events depends greatly onrnthe physical hydraulic and mechanical properties of soils. Increasing numbers of extreme events in winter time in recent years haverndemonstrated the paramount importance of effective and integrated management of land resources in the protection of the environmentrnand of the road network. In Italy more than 10% of the territory has been classified as having a high or very high hydro-geological risk,rnaffecting 80% of the Italian municipalities. The impacts on population and the economic damages are relevant. In Italy over the last 20rnyears, floods and landslides had an impact on more than 70 000 people and caused economic damage of at least 11 billion euro. Sincern2000, the Italian Ministry for the Environment entrusted ISPRA the task of monitoring the programmes of emergency measures tornreduce hydro geological risk. (ReNDiS project, database of mitigation measures against floods and landslides).
