SOLUÇÕES PARA DRENAGEM: eventos de inundações ocorridas na Avenida Oswaldo Cruz, no município de Três Pontas

Abstract

The main factors that cause the floods are the impermeabilization of the contribution basins and the disordered occupation of the urban areas. The Oswaldo Cruz Avenue, located in the municipality of Três Pontas - MG, has relevant flood histories during periods of intense precipitation, causing damages to the population. For a proper drainage system proper administration of the municipality is required, as well as the correct investment. This work has the purpose of analyzing the study site and its contribution basin, as well as identifying the existing macrodrainage system, with the purpose of correcting due errors, with correct methods. For this, a bibliographical review was carried out, hydraulic and hydrological surveys of the avenue in question. In this way the characterization of the existing drainage system was made. With all the data collected it was possible to carry out the dimensioning of the section under study, to characterize the existing problems in the macrodrain system and to indicate the best solution to the problem, elaborating a project with viable solutions for the canal, such as concrete wall cladding not finished for smooth concrete in order to reduce the Manning coefficient, aiming to increase the hydraulic capacity, the resizing of the stretches, and the use of gabion and vertical step, to reduce the flow velocity. All the techniques used will be presented in the descriptive memorial.
