Abstract: The high hydrodynamism in harbours involves the sedimentation of pollutant substances. Some of these substances could have a toxic character, like heavy metals. In this study, a number of chemical analyses were carried out on samples taken from the studied area. The results were treated using software, which enables us to distinguish the dredged sediment according to their contamination leveland there potential toxicity. Using a simplified method, the already mentioned software allows determining the risk levels taking into account the actual codes. The occurred changes of the velocity field, favourite the transport of these substances and their sedimentation in harbours. The simulation of the hydrodynamism and the sediment transport were made using the models RMA2 and SED2D. Hence, solutions to the localisation of the sedimentation areas can be achieved in order to facilitate the dredging operations. A reduction of the sediment intrusion is possible when an appropriate harbour basin conception is considered.
