Controle do assoreamento e dos contaminantes por meio da gestão de bacias hidrográficas para o planejamento das dragagens portuárias na baía de Antonina/Paraná/Brasil

Abstract

The threat of port activities becoming unfeasible due to maintenance dredging costs, as is the case of the Port Terminals of Ponta do Felix, makes it necessary to investigate the origins of the silting process, as well as of the contaminants that are present in the sediments found in the Antonina Bay, located at the coastline of the Sate of Paraná. The purpose in this part of the research, developed within the CSD Programme, was to characterize the relevant physical-natural aspects that could help in the investigation and understanding of the growing silting in this bay, which has drainage area that totals 1,621.5 km2.
