GIS-based predictive models for regional-scale landslide susceptibility assessment and risk mapping along road corridors

摘要: ABSTRACTIn this paper, a study aimed to assess the landslide susceptibility at regional scale for wide provincial territory of Matera (Basilicata region, southern Italy) and relative risk along main road corridors distributed in area is presented. A heuristic-bivariate statistical predictive model was performed map by using polynomial function eight predisposing factors, weighted according their influence on instability process. The resulting successively used assessing network. importance these roads, representing network connecting urban centres, derives from absence an efficient integrated transportation system through entire territory. evaluated matricial approach, which has allowed define levels (low, medium high) stretches overlapping th...
