Estudo de caso: Impactos do crescimento urbano na drenagem da cidade de Sapezal - MT

Abstract

The growth of urban centers has several impacts on the environment, which must be studied and controlled to maintain order and people's safety. Therefore, one of the systems that is largely neglected in most cities is the rainwater drainage system, as it has, in most cases, low socio-political engagement in proposals for implementation, expansion or maintenance due to various electoral factors and common knowledge . Therefore, this work aims to evaluate the efficiency of the existing drainage network in the municipality of Sapezal, located in the state of Mato Grosso, through the use of two stages of analysis. In the first stage, the Storm Water Management Model (SWMM) program is used, which can be understood as Stormwater Management Model (MGAP), to assess the behavior of the water flow in the pipelines and manholes of the existing network in the municipality. . From this, it is possible to obtain the minimum diameters necessary in each stretch of the existing network in order to ensure that the manholes and network conduits are not overloaded. The second stage refers to a comparison between the number of wolf mouths existing in the city and the quantity scaled according to known calculation methodologies. In this way, the difference between these two distributions is obtained, in which the amount of existing mouths is equivalent to approximately 30% of the dimensioned amount. With this, it is possible to identify points of the network that are more overloaded, as well as discuss the possible socioeconomic damage that this difference causes.
