Storm surges displace thousands of tons of sand between channels along the Santos shoreline and force the City Hall to maintain frequent operations with heavy machinery to preserve urban drainage, reduce flood risks, and reorganize sediments carried by the sea’s force.
In Santos, on the coast of São Paulo, storm surges have begun to require frequent operations to remove sand accumulated in the shoreline channels and maintain the functioning of urban drainage in flood-prone areas.
According to the Regional City Hall of the Shoreline and Intermediate Zone, each episode of rough seas can displace between 2,000 and 3,000 tons of sediments along the sand strip.
The impact occurs because the sea’s force alters the natural distribution of sand on the beach and pushes part of the material into the channels.
