Gestão de águas pluviais: Um diagnóstico dos dispositivos de microdrenagem da Avenida Ministro João Alberto na cidade de Aragarças-GO

Abstract

With the urbanization occurring in an abrupt and growing way allied with the reduction of too many permeable areas, we have an increase in the velocity of surface flow. For this reason, an efficient drainage system is necessary to prevent, bypass and minimize the possibility of inundation or flooding. In this aspect, the present research has the objective of verifying the effects of urbanization in the drainage system installed on the road within the perimeter between the bounded points of the Avenida João Alberto avenue in the city of Aragarças-GO, producing a diagnosis of the current performance of the devices of this system. For that, it was carried out from an applied methodology and explanatory the characterization and quantification of the devices that compose the current drainage system, in order to enable the understanding of the situation in which the devices meet. Consequently, it was possible to understand that the fragility state in which the drainage system is located is in fact the result of the effects of the accelerated urbanization process, which directly culminates in a critical scenario, since 68.84% of the linear meters of the has no gutters, damaging 86% of the gratins. The current sizing is also insufficient for the road, and the gutter, curb and sidewall devices present in the system are still damaged along the way. Therefore, the completed diagnosis of the pathway is that the current system is in a critical situation, requiring a process of resizing.
