摘 要：This study investigated the risk of flooding along the Sao Paulo city＇s railway network and showed its latest technologies. To that end, we took into account topographic and hydrological features, as well as possible interferences of the flooding phenomenon with the optimal operation of the railway system. When preparing the maps and the flooding risk analysis, we used data from project SRTM （Shuttle Radar Topography Mission） integrated and processed in a GIS （geographical information system）, through version 2.14 of the geoprocessing software ＂QGis＂. Results showed risk exposure for logistics operations of the railway system for the transportation of passengers, especially in the Central and Eastern regions of the city, where there is a higher concentration of points of flooding, thus making it more difficult for passengers to come and go in the greatest city of Brazil.
