Floods represent one of the most frequent and complex problems in urban areas worldwide, causing damage to inhabitants and to their economic activities. The city of Rio de Janeiro has a long history of floods, formerly related to topographic and climatic characteristics, which, in the course of the occupation process and urbanization started in the sixteenth century, were enhanced by the physical environment interference held up by public policies. This Master s Thesis aims to analyze the causes of flooding, as well as its implications in the space organization, in the downtown area of Rio de Janeiro, showing former and later forms and processes. Flooding in the city center were mapped with demarcation between equivalent sectors, where are evident the most critical areas of occurrence, because of the damage caused by the floods. Hence, the work was based on a literature review and field work. Recommendations from the results of the surveys and analysis carried out are also made, in order to contribute to initiatives that seek effective solutions to the old problem of flooding in the central area of Rio de Janeiro. As a result, we can conclude that a number of factors combined contribute to the current occurrences, those embedded in a more local scale, such as the leveling of the streets, which still has old city s features or the inefficiency of the drainage network, as well as more extensive factors, linked to topography and associated drainage.
