Árvore de falhas como método de identificação de processos associados ao desenvolvimento da eutrofização em reservatórios

Abstract

Water security is associated to both water quality and availability, and on regions that are periodically dealing with scarcity issues, as the Brazilian semiarid region, is important to correctly know water related processes and its development. In this context emerges eutrophication, an aquatic unbalance related to human interference, which is related to reservoir’s location, geometry and increases on nutrients concentrations. The aim of the present study was to develop a fault tree for the eutrophication problem, incorporating discussions and systematizing the events involved on the degradation of water quality. The results showed the complexity of the system and discussed its processes, aside from organizing the issue’s origin with the development of a fault tree. It was concluded that the fault tree developed can be used as an auxiliary tool on the water resources management.
