Sistema de drenagem urbana para captação, transporte e desague de águas pluviais: um estudo de caso sobre a avenida São Carlos, situada no bairro Olho D’agua em cidade de São Luís

Abstract

The work in question presents a case study regarding the drainage work on the São Carlos avenue, located in the neighborhood of Olho d’agua, São Luis Maranhão. Based on visits and analysis of the site, we found that the drainage system developed was made entirely complete without any more elaborate drainage system on the avenue, since the avenue itself, having a high slope index, was used for many years without the presence of a complete and effective system. The study was based on data and photographic reports from the site in question, in addition to projects made for the site. AutoCAD-2015®, Google Earth Pro®, GoogleMaps® and Excel®, with photographic records, of the entire analyzed area, and obtaining the projects used. Based on studies carried out in the study area, in view of the absence of a previous system, the inefficiency of the existing drainage method was found. Knowing the contribution flows, concentration times and the rain equation of São Luís, a project of new dimensions and components of the system was elaborated and dimensioned, works of art of microdrainage that will allow the viability of the rainwater drainage in the study area and its transport to a suitable location.
