Análise de risco em barramentos

Abstract

In Brazil, dams play an essential role throughout the national territory. However, before the enactment of Law No. 12,334 on September 20, 2010, which established the National Policy on Dam Safety and created the National System of Information on Dam Safety, data related to these structures were not readily available. This made dam safety control a challenging task. Throughout all phases of dam construction, safety must be considered from the beginning of the project. Risk analysis plays a fundamental role in defining safety plans, providing crucial data for the development of a secure project capable of withstanding statistically identified potential events, based on the site's characteristics where the construction will take place. This translates into a significant reduction in incidents and the goal of completely eliminating dam accidents.This article aims to identify the main causes of incidents and accidents in dams in Brazil, as well as analyze the evolution of the supervisory authorities' actions in monitoring the state of these structures. Through these measures, the aim is to ensure dam safety, protect the environment, and safeguard the lives and property of the communities that rely on these structures for various purposes, such as water supply and power generation. It is crucial for the country to continue improving its system of regulation and monitoring to prevent tragedies and ensure the well-being of its citizens.
