Simulação da propagação da onda de cheia causada pelo rompimento hipotético da barragem do Rio do Cobre e delimitação da área de inundação à jusante, Salvador - Ba

Abstract

This article aims to analyze the impact caused in the channel downstream of reservoir considering the hypothetical rupture of the Cobre’s dam, Salvador, Bahia, through the application of the HEC-RAS model. Therefore, the methodology was divided into three stages: Construction of break hydrograph, Survey data necessary for mathematical modeling and propagation of the flood wave downstream from the reservoir through hydrodynamic one-dimensional model. The analysis showed that the hypothetical dambreak of the Cobre’s Dam caused the flooding of regions with a high degree of urbanization. In the preparation of the Emergency Action Plan this area should be considered and evacuation measures need to be discussed with the community to mitigate human losses in a possible rupture. It should be emphasized that this study has uncertainties which should also be taken into account.
