Análise Espaço-Temporal da Pluma de Dispersão dos Sedimentos Dragados do Porto de Maceió, Alagoas

The understanding of the sedimentary dynamics is important in characterization impacts caused by dredging and this knowledge becomes decisive for their discernment. aim article was to analyze plume dispersion sediments Port Maceió. analyzes were carried out three sampling campaigns, before, during after port works, which collection points discard areas plotted. suspended particulate material (SPM) analyzed using gravimetric method situ parameters turbidity, dissolved oxygen percentage saturation, salinity electrical conductivity with a multiparameter probe water transparency Secchi disk. SPM, turbidity linear interpolation, while other variables subjected analysis on polynomial calibration curve. multiparameters worked submitted box plot order assess variance between campaigns. variation SPM sample campaigns showed dynamic spatial temporal behavior; interpolation promoted better visualization physical that directly express dispersion; supplementary trend patterns relation sediment charge; Box proved be pertinently useful evaluating interpreting results an integrated manner, mainly due large number analyzed; works had balanced management amount dredged disposition at site when compared area.
