For the enlargement of the nautical dimensions of Santos Port Outer Access Channel (Brazil), training walls crossing the Offshore Bar are needed. The training walls choice to reduce dredging rates also induces to consider a coupling planning between nautical purposes and shore protection measures, as Santos Municipality have serious erosion problems nowadays due to the urban growth in the backshore and sea level rise. For decision support, the Hydraulic Laboratory of Engineering School of University of Sao Paulo was commissioned to study in a composite mathematical and scale model. Results include changes in wave height and direction and current speed analysis to conditions with training walls and segmented breakwaters. The water renewal was also analyzed to the condition with segmented breakwater and compared to current situation, based on hydrodynamics results and considering that this structure can reduce water quality in this area.
