Metodologia de riscos para reservatórios: aspectos de qualidade de água

Abstract

Risks are inherent in any activity, they must be managed and never neglected. They are measured by their probability of happening and their impact on the occurrence. There are numerous studies on dam risks, projects, construction, equipment assembly, among others. However, there is still a gap to be developed regarding the specific risk assessment methodology for reservoirs, which requires further studies and analysis. The reservoirs that are an integral part of hydroelectric projects have the purpose of accumulating water for energy generation, especially in the dry or dry season and need to be better understood, studied and analyzed, specifically with regard to risks. In Brazil, in the last two decades, water shortages have already occurred in several states. The objective of this dissertation is to develop a risk assessment methodology for reservoirs. As main products are: the risk assessment methodology for reservoirs, spreadsheet for automating the methodology, frameworks for risk identification and the risk methodology for dam safety. The methodology will be developed in the following steps: 1. Analysis of the national and international bibliography on the subject; 2. Elaboration of the assessment methodology for dam safety; 3. Elaboration of risk analyzes using the Event Tree Analysis (ETA), Failure Mode, Effect and Criticality Analysis (FMECA) and Ishikawa frameworks and 4. Elaboration of the risk assessment methodology for reservoirs and the development of the spreadsheet for automating the calculation of the methodology.
