Segurança de barragens brasileiras: uma análise comparativa entre a região sul e o estado do Paraná com base nos dados cadastrados no SNISB

Abstract

The present study proposed a comprehensive comparative analysis of dam safety data in the Southern Region of Brazil, with a special focus on the state of Paraná. The main objective was to conduct a quantitative assessment to map the situation of this state regarding dam safety in the region. The research was based on data extracted from the National Dam Safety Information System (SNISB), providing a detailed approach to the number of registered dams in the region and their respective risk levels. Additionally, the study aimed to identify and analyze the most relevant aspects related to the safety management of these structures. By offering a comprehensive view of dam safety data, this work sought to contribute to the understanding of the past landscape and potential areas for improvement in dam safety management in the Southern Region of Brazil, with a special emphasis on the distinctive characteristics of the state of Paraná. The results are alarming regarding the lack of information, registration, and classification of most dams in the Southern Region of Brazil, and the same case applies to the state of Paraná.
