Abstract
In connection with the design of new marine facilities a hydraulic study was carried out at Pecém, NE Brazil The project comprised mathematical modeling of waves, nearshore hydrodynamics and sediment transport before and after the construction of the offshore harbor in front of Ponta do Pecém. The wave conditions are characterized by the simultaneous occurrence of sea and swell from different directions. The littoral current generated by the sea becomes detached at the headland. A shore-connected spit develops under these circumstances. During periods of predominant swell the spit erodes. The main impact of the harbor is a further reduction of the littoral drift W of the headland, which causes increased sediment accumulation immediately W of the headland and coastal erosion W of the city of Pecém.
