Challenges in Understanding Sediment Flow in Lago Grande de Curuai in Central Amazon
A 2D Numerical Modeling Approach
Palavras-chave:
Floodplains, Computational Modeling, Sediment TransportResumo
Este estudo investigou a dinâmica sedimentar na planície de inundação do Rio Amazonas por meio de simulações com Delf3D. A vazão média pelo Lago Grande de Curuai foi de 5.000 m³/s, ultrapassando os valores observados em mais de 2%, com picos podendo exceder 20.000 m³/s. Padrões sazonais de concentração de sedimentos (fev a set) foram identificados. Apesar de defasagens nos picos simulados em relação às observações, as simulações ofereceram informações cruciais sobre a dinâmica de transporte de sedimentos na região, fundamentais para tomadas de decisões informadas e proteção ambiental.
