Methodological procedures to landslide risk mapping in Brazilian slums

Abstract

This essay presents the methodological procedures and criteria to landslide risk mapping on urban settlement unstable areas (slums) in Sao Paulo (Brazil). The methodology was developed by researchers of the Instituto de Pesquisas Tecnológicas (Institute for Technological Research - IPT), with the collaboration of other professionals, based on their own experience. The procedures are determined based on geological and geotechnical investigations, probability analysis of the occurrence of processes related to external dynamics, identification of risk areas, analysis of possible consequences of the processes and information of appropriate intervention measures for the different cases. © Springer-Verlag Berlin Heidelberg 2013.
