Análise do escoamento laminar de uma via no município de Campo Mourão – Paraná

Abstract

Considering the increase in the population rate of urban areas since the mid-twentieth century, it can be observed that in several cities there has been disorderly and poorly planned growth, resulting in an increase in impacts on the urban environment such as floods, inundations, and resulting river contamination. In view of this problem, it becomes necessary to reduce the volume of rainwater drained into drainage systems by increasing soil permeability through the implementation of sustainable solutions that drain and store precipitation, thus reducing peak flow. Therefore, the present work aims to evaluate the drainage project of a road in the city of Campo Mourão, Paraná, comparing laminar flow with sustainable pavement. To this end, four pavement conditions were analyzed, identifying the differences in flow in each case, using Runoff coefficients applied in a study area of 3,517.41 square meters to compare the runoff rates. Situation 3 obtained the best result, as it showed a flow of 34.42%, thus infiltrating 65.58%. This infiltration of water into the soil has several benefits for the environment and society as a whole. Firstly, it helps to maintain the balance of the hydrological cycle, contributing to the reduction of the risk of floods and inundations, as the water is absorbed by the soil and does not accumulate on urban surfaces.
