INUNDAÇÃO EM ÁREAS URBANAS: Estudo de Caso Canalização Ribeirão Araras Três Pontas - MG

Abstract

This study aims to study the stream conduit features Araras, in the city of Three Points, south of Minas Gerais within its capacity because of frequent flooding and structural problems in the main drainage device along the Oswaldo Cruz Avenue . Floods are natural phenomena characterized by overflowing streams and when they reach urban environments can cause serious economic and social problems. They used statistical models to define the maximum flow, where the area of the drainage basin and regionalized series of basins flows with similar characteristics was raised to recommend payback period and compared with the flow supported by channel by the empirical method Manning. It was found the channel transport inability to maximum flows with a return period equal to or longer than ten years and problems such as instability of the channel section maintenance problems. Thus it was proposed a new section to the appropriate payback period and maintenance and prevention measures.
