This subproject aims at the identification and quantification of transport processes, morphodynamics and major aspects of water quality around the harbour and in the central bay of Paranaguá. A priority item is the investigation of anthropogenic impacts due to dredging, dumping and harbour-derived input of matter on the morphodynamics, siltation and water quality in the area near Paranaguá. Accordingly, the study refers to work packages WP 2 and WP3 of the joint project.

To achieve the goals of the project a combination of field measurements and numerical models for the simulation of hydrodynamics, sediment- and morphodynamics within the bay of Paranaguá will be applied. From the model scenarios, options for the optimisation of dredged material management will be derived. On the basis of comprehensive field investigations and existing data sets the significance of nutrient inputs (C, N, P) and entero-bacterial emissions from sewage and harbour operation for the water quality status in the vicinity of Paranuaguá will be assessed. These data will be used for the development of a water quality model to simulate the dispersal and transport of pollutants in the area. The respective scenario runs form the basis for the formulation of mitigation strategies and contingency plans as well as for the definition of future monitoring concepts.

In addition to the research activities described above, the overall coordination of the joint project will be performed within this subproject.
