Proposta de técnicas de controle da erosão às margens da PR-317 entre Floresta e Peabiru

Abstract

The erosion processes occur of natural form tease by the wind, water and climate agente. Such process is caused by the shallow flow of the groud, enabling appaearance of grooves, ravines and gullies in region with high favoring mudslide. The erosion also can be acceleratedby the out of human occupation. The case repeats where there are construction in which aren’t preventive measures application necessary. This way, this job have the aim to propose technique of erosion contention through of the soils Bioengineering in the highway PR-317 between Floresta and Peabirú. How case study for this job was performed the median gutter sizing of concrete end of to get data about the support of the volume of water and check if the water blade exceeds the recommended in project. The concrete channel leakage of the sizing will be able to favor the appearance of erosions in the edges affecting the traffic performance. This way, was accomplished a comparison of the performed the median gutter sizing of grass with the concrete gutter checking the capacity oh the flow rateof water due (decorente) of the superficial flow. The results in the case study show that the estimate characteristic hydraulic flow in the gutter designed in concrete introduced water height close the limit of the sizing and maximum velocity of 3,30 m.s-1. This velocity was five times higher than estimated to the limit to grass which was found maximum velocity of 0,65 m.s-1 with maximum height of 0,28 m.
