ABSTRACT

The enlargement of the nautical dimensions of Santos Port Outer Access Channel (Brazil), with the purpose of receiving vessels between Post Panamax Plus and New Panamax, 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. Indeed, the beaches of Santos Municipality have serious erosion problems nowadays due to the urban growth in the backshore, sea level rise and the increasing effect of extreme events of storm surges. For Port and Municipality Authorities decision sup-port, the Hydraulic Laboratory of Polytechnic School of São Paulo University was commissioned to study in a composite mathematical and scale model, evaluations about the morphological impacts of the training walls, considering the nautical purposes and a compatible solution for the shore protection structures.
