Eficiência hidrológica de pavimentos permeáveis em áreas urbanas: estudo aplicado em Teresina - PI

Abstract

The rapid urbanization of cities has created a series of challenges, especially regarding the efficient management of stormwater runoff. Conventional paving, which makes the soil impermeable, significantly contributes to problems such as flooding, inundation, and damage to urban infrastructure. These extreme events not only result in significant economic losses but also profoundly affect the quality of life of residents and the regular functioning of cities. The study addresses the effectiveness of permeable pavements as a sustainable alternative to mitigate these issues, focusing on the city of Teresina-PI. The study was conducted using the SWMM (Storm Water Management Model) software to model and simulate the hydrological behavior of a subdivision, comparing scenarios with and without the application of permeable pavements. The results indicate that the implementation of permeable pavements can significantly reduce the total runoff volume by about 24.00%, decrease the peak flow by approximately 57.00%, and increase the drainage system's response time by up to 7 minutes, meaning that the water takes longer to reach the peak runoff. These pavements also promote water infiltration into the soil, enhancing the recharge of underground aquifers. The study highlights the importance of permeable pavements as a sustainable and effective solution to mitigate flooding problems in urban areas, contributing to more efficient stormwater management in Teresina.
