Análise das condições de segurança de barragens da Região do Vale do Jaguaribe do Estado do Ceará

Abstract

Drought is one of the main problems faced by the population of the Região Nordeste, the irregular rainfall regime and high temperatures are determining factors for the worsening of this situation. In order to reduce this problem, dams are built to be able to reserve water, and thus be able to ensure the use of water throughout the year. However, these structures have great risks, because a rupture of a dam can cause damage from loss of life to economic, social and environmental damage. The main objective of this work was to evaluate the safety conditions of dams in the Jaguaribe Valley region, in the interior of the State of Ceará. The nearest dams in the city of Russas were selected, where the UFC campus is located. Inspections were carried out, following the recommendations of the Dam Safety and Inspection Manual of the Ministry of National Integration. We sought to identify points that require greater attention to maintain the structures that make up the dams. During inspections, it was possible to observe the presence of some anomalies in the structures belonging to these dams. None of the anomalies identified indicate the risk of imminent rupture of the structure, resulting from both the natural degradation of composition materials and poor or non-existent maintenance. It is then noted the importance and need to monitor these anomalies and carry out further studies on their causes so that the level of risk of rupture of these works can be adequately evaluated.
