SOLUÇÕES DE DRENAGEM: EVENTOS DE ENCHENTES OCORRIDAS NO RIBEIRÃO SANTO ANTÔNIO

Abstract

With most of the population in the urban area, it is natural to assume that there is a considerable increase in impervious areas. Population growth, river and lake margins have become considerable places of habitation, but without proper management. This paper demonstrates how this occurs in the city of Campanha MG, where the population occupied areas close to Ribeirão Santo Antônio and end up suffering from annual flooding during periods of heavy rainfall. In order to show the problems encountered, as well as the reason for the flood and flood events in the region, the study was conducted in front of Ribeirão Santo Antônio, focusing on the macrodrainage system of the watercourse. With this, it was possible to elaborate solutions and projects that aim to cease this problem, in this case it was approached as a solution the material exchange, with the alteration of the channel roughness. This change has increased the support flow capacity of the channel, so that it is higher than the system imposes, and thus found the solution to this adversity.
