Uso de micro reservatórios para controle do escoamento superficial

Abstract

Urban growth has modified the natural hydrological cycle, since large areas have become impermeable, consequently causing major flooding in the urban environment. In the search for a solution to this problem, urban drainage has emerged, aiming at the rapid removal of rainwater. However, traditional solutions proved inefficient, as they only displaced the problem from one place to another. Over the years, new solutions have emerged that aim to mitigate the problem of runoff. This study sought to compare the use of traditional drainage methods and the compensatory methods of urban drainage, the micro reservoirs. The study was carried out in the sub-basin PE04, located in the Parque Sul neighborhood, Teresina, PI. For the simulation of the scenarios the computer program SWMM, version 5.1, was used, where two scenarios were modeled. After the simulations, it was found that with the use of the compensatory drainage method, there was a mitigation of the runoff flow in the sub-basin PE04.
