Short summary
Porto Alegre lies within a river junction that has become an important alluvial port as well as a chief industrial and commercial centre. This strategic location resulted in severe damage by flooding. Consequently a complex system of levees and pump stations was implemented during 1960s and 70s. In recent years, the levees were severally criticized by city planners and population due to the false perception of lack of flood risk as since its construction, not a single large flood event occurred.
