Impact of climate change on the harbours, land areas and wetlands of Sao Paulo State Coastline (Brazil)

Data set obtained from a scale model of the whole area of Santos Bay, Estuary and nearby beaches (Brazil) showed the impact of maritime climate changes, wave climate and tides upon harbour and coastal structures maintenance, beaches stability, tidal inlet saline intrusion and wetlands flooding. Considering the increasing sea hazards, the high values of the facilities and infrastructures in São Paulo State Coastline, it is necessary to mitigate the risks from the point of view of the harbour and coastal structures maintenance and projects purposes increasing defences procedures. Hence, are highlighted guidelines strategies suggested for Access Channels dimensions, wharves free-board, jetties and breakwaters dimensions, dredging rates, rigid and flexible littoral defences, saline intrusion and land protection against flooding (including wetlands).
