Avaliação da influência da urbanização no regime de escoamento superficial do Rio do Campo nos bairros Condomínio Rio do Campo, Residencial Parque do Lago e Novo Royale Premium

Abstract

With technological and population advancemente, humans have heavily modified natual resources to meet the need for comfort and well-being. For a long time, measures were not taken to minimize impacts. Less developed countries, including Brazil, experienced a rapid urban expansion in a short period of time, with poor drainage infrastructure combined with low levels of awareness, leading to recurring flooding for populations. Thus, this study aims to evaluate the influence of urbanization evolution on the surface runoff regime of the Rio do Campo river in the neighborhoods of Condominio Rio do Campo, Residencial Parque do Lago, and Novo Royale Premium. To estimate the time of concentration of sub-basins, the equations of Kirpich, Carter and Ven te Chow were used based on dydrographic characteristics. The region was divided into two sub-basins, one including the left bank of the Rio do Campo river and Residencial Parque do Lago, and Novo Royale Premium. The surface runoff showed and abrupt increase in flow between the currently modeled and futur projection, with a difference of 56.64% between their values, with the peak flow of 39.71 m3/s occurring after 65 minutes of precipitation. The tributary presented similar values for comparing current use with future projection. The hypothesis that soil sealing can increase in flow with the advancement and growth of the city, was confirmed, raising other questions about how to minimize its impacts in a viable way and with minimal.
