Proposta de sistema de microdrenagem urbana para o bairro Maternidade no município de Patos/PB.

Abstract

The disorderly urban expansion causes numerous problems and inconveniences to the environment and the population, this process negatively affects the permeability of the soil and the natural flow of precipitated water, consequently, such problems favor the emergence of floods and floods, to the detriment of this, the rainwater drainage systems as a way of compensating for the impacts arising from this process of unstructured land occupation. This study aims to present a proposal for a technical solution for the Maternidade neighborhood located in the municipality of Patos-PB, which has been suffering from constant flooding, causing inconvenience and damage to the residents of that neighborhood. Bibliographical research, planialtimetric survey, study of soil use and occupation and obtaining hydrological parameters were necessary for the design of this project. With these data, the dimensioning of the hydraulic structures was carried out. Finally, it was verified that 49 stretches of gutters do not support the design flow, requiring the implementation of 144 grate-type culverts without depression and 1,844 meters of storm sewers.
