Damage of the rio all the saints in the valley of mucuri/mg: analysis of break-down for Teófilo Otoni

Abstract

Major engineering works aredesigned to solve or minimize problems. This work presents a study on the dam that aims to supply and satisfy the needs of the region, but which can generate some inconvenience if the bus breaks. In this way, the research evaluated the flood waves from the hypothetical rupture of the Teófilo Otoni-MG dam. For the accomplishment of this study was used the method of the characteristics described by Mascarenhas. The calculated maximum rupture rate was 5739.34 m³ / s, using the simplified triangular rupture hydrograph. The estimated time of emptying the reservoir is approximately 4,460.44 seconds (1.24 hours). On thebasis of the data found, we noticed that the municipal seat of Teófilo Otoni, located 15 km from the dam, would be hit by a fencing phenomenon, whose height would be approximately 3 meters. It is observed in this conclusion that the results obtained in the development of this study proposal can increase the possibilities of actions related to the prevention of catastrophes, with respect to the construction, maintenance and involuntary rupture of a barrage of containment, and to encourage emergency strategies support, in case of imminent risk situations.
