Gis-based method for geomorphological impact assessment on a railway track in province of Modena (Italy)

Abstract

This article illustrates a model for the assessment of geomorphological impacts and risks related to the construction of an high speed railway track. This model fits into general multi-criteria analysis methods based upon the use of GIS techniques, and has been tested in the study area of Castelfranco Emilia (Province of Modena, northern Italy). The core of the analysis is based on a series of crossing operations between thematic maps that enable the network of mutual interrelationships between geomorphological component and the alternative for the project to be outlined in impact and rick matrixes of maps.
