Proposta de melhoria do processo de definição da área diretamente afetada pelo rejeito nas regiões encobertas pela vegetação: estudo de caso: Barragem B1 da Mina Córrego do Feijão – Brumadinho - MG

Abstract

On January 25, 2019, B1 Dam in Feijão Mine, located in Brumadinho, MG, collapsed. The mapping of the Directly Affected Area (DAA) by the rupture is used by several Environmental documentations, hence the importance of its correct delimitation for strategies of reparation. The density of the local vegetation made it hard to the precise mapping of the Directly Affected Area. This dissertation aims to propose a new methodological form for delimiting the DAA, presenting the process of revising the affected area perimeter, describing the technologies used in the process, and comparing the perimeter elaborated by traditional methods with the newer ones found by this study. As a complement, this article presents an implemented proposition to the methods, describes how it was useful to support operations of rescue teams in the affected area, and presents the possibility to use it on mass displacement events in general.
