Disorganized growth and urbanization have a direct effect on drainage systems and urban flooding. With the urban development occurs the waterproofing of the soil, the water that infiltrates in the ground or was retained in the plants passes to flow through the conduits demanding greater capacity of flow of the sections. The quantification of the impact of urbanization on the runoff can be done through mathematical models that appear as an important analysis tool for the ability to provide answers to different scenarios resulting from possible design measures. When floods are recurring in an already urbanized basin and with a drainage system already in place, the computational tools allow the simulation of the network by locating the critical points in the face of a project precipitation. In this context, this work of course conclusion sought to analyze the behavior of the rainwater drainage system of an urban water basin, located in the city of Uberlândia, Minas Gerais, using the SWMM computational tool. The site studied is the Avenida Professora Minervina Cândida de Oliveira which is widely used by the population, and was built on the channel Tabocas stream. The water catchment area of the Tabocas stream now presents totally urban characteristics, having in its occupation a predominance of waterproofed soils. The present study considered the behavior of the system for the current scenario of occupation of the basin with 80% waterproofing of the areas. From the simulations for project rainfall with a 20-year return period, the results generated showed that, for the current scenario, the system is not able to satisfactorily discharge the flows in some stretches. Therefore, it is verified that the waterproofing of the basin and the undersizing of the drainage works generate conditions for the occurrence of overload in the drainage conduits and flooding problems.
