Avaliação do índice de fragilidade do sistema de drenagem pluvial urbano. estudo de caso: Centro de Mossoró.

Abstract

The system of urban drainage of rainwater is of extreme importance in the present day, with the increase of urban expansion there is a need for constructions of houses, buildings, roads and etc. In this way, the knowledge and applicability of a good rainwater drainage system is important, since this growth generates impacts on the water infrastructure, thus affecting the system and the hydrological cycle, generating floods, which is one of the main problems of large cities, not only The system is affected, but also the set that governs public policies, master plan, basic sanitation, etc. Then from the problems arising from failure in the drainage system, there is a need to take measures that are classified as structural rather than structural. Therefore, the present study aims to analyze the urban drainage system through the application of a methodology based on indicators of system fragility and provide actions, measures that improve the control and protection aspects in the flood areas of the area. Defined study, which is the center of the city of Mossoró/RN.
