Modelagem Ecológica como Ferramenta Auxiliar para Restauração de Lagos Rasos Tropicais e Subtropicais

Abstract: A crescente produção de carga orgânica e de nutrientes em bacias hidrográficas tem levado, historicamente, lagos rasos a drásticas mudanças na qualidade da água, na diversidade e riqueza biológica e nos usos nobres de suas águas. Estes ecossistemas aquáticos podem ser caracterizados, de uma maneira bem simplificada, por dois estados alternativos de equilíbrio: (a) um estado de baixa turbidez com predominância de vegetação aquática submersa, baixos níveis de biomassa fitoplanctônica ou (b) um estado de alta tur… Show more

“…Nevertheless, modeling the metabolism dynamics in subtropical reservoirs linked to its watershed is still incipient. Therefore, this work aims to evaluate the temporal variability of metabolic rates by applying the process-based model IPH-ECO (FRAGOSO JÚNIOR et al, 2010) as well as the responses of the Faxinal reservoir to different inflows from the watershed, which was simulated by the hydrological model IPH-II (BRAVO et al, 2007). The analysis of the temporal variation of metabolism in Faxinal reservoir through the simulation of biogeochemical and hydrodynamic processes lead to the answers for the following questions: (a) Is there any relationship between the metabolism of the reservoir and its watershed in terms of inflows and nutrient loads?…”
