Estudo do sistema de drenagem urbana dos bairros Shangrilá I e Shangrilá II no município de Campo Mourão, Paraná

Abstract

With the growth of the cities and the increase in population, it has become extremely necessary for de the development of urban infrastructure to be proporcional to these factors. Urban drainage is essencial to the cities planning, because when structures inefficiently it can cause problems with flooding and destruction of built areas, directly impacting the population’s quality of life. For the dimensioning of the items constituting the drainage network, the rational method is user, the rational method is used, which taking into account the characteristics of the soil, intensity of precipitations and areas of contribution of surface runoff presentes the suitable diameter so that the pipes are calcuated in na economical and safe way. Based on theese premises and guided by scientific studies, the presente work addressed, as na objective, the study of the drainage system of the neighborhoods Jardim Shangrillá I e II in the municipality of Campo Mourão, located in the Northwest region of the State of Paraná. Through the map of the city’s rain galleries, it was possible to obtain the rainwater collection points, as well as the emissaries. Through the rational method, the drainage network was dimensioned and it can be oserved that in some sections the flow velocity is well below the recommended limits, which may generate flooding, so it is advisable that in order to avoid future problemas, the diameters of some sections of the galleries be reviewed and expanded.
