The circulation of the lower Capibaribe Estuary (Brazil) and its implications for the transport of scalars

O estuario do Rio Capibaribe e um corpo de agua que atravessa a Regiao Metropolitana de Recife (RMR), um dos maiores centros populacionais do Brasil, o que causa grande quantidade de carga de poluentes e baixa qualidade da agua. A entrada de agua doce a partir das aguas residuais da RMR pode contabilizar mais de tres vezes a contribuicao fluvial durante o periodo de baixa descarga. Este artigo investiga a hidrodinâmica e o potencial transporte de escalares particulados e dissolvidos neste estuario. Um experimento de campo foi realizado para registrar nivel da agua, velocidade de corrente, salinidade, temperatura e material particulado em suspensao (MPS) durante um ciclo de mare semidiurno completo. O experimento foi realizado em condicoes de baixa descarga e em condicoes de mare de sizigia. O estuario apresentou padrao de circulacao parcialmente estratificado. O transporte residual de agua e sal foi estuario acima, enquanto que o transporte residual de MPS foi estuario abaixo. Os primeiros sao entendidos como o efeito da complexa circulacao ao redor das ilhas que formam o baixo estuario, enquanto que o ultimo foi interpretado como devido a efeitos morfologicos que induzem a ressuspensao durante a vazante, a despeito da simetria entre correntes de enchente e vazante. Este mecanismo pode produzir transporte para a plataforma adjacente, mesmo durante periodos dominados pela mare, quando o oposto seria esperado.
