A practical application is dealt with in the present study, whose purpose is firstly the modelling of hydrodynamics in a coastal basin located in the Southern Italy and secondly the simulation of dredged sediments in the same area. On one side, the Protected Marine Area of Porto Cesareo, instituted in 1998, has produced great benefits to the coastal town in terms of environmental conditions improvement, but on the other side it has penalized some social, tourist and economic aspects, forbidding many kind of activities along the coastal area. Particularly, some interventions are necessary to guarantee a safe mooring for local fishing boats, by respecting all the environmental restrictions. In this research, once analysed some circulation patterns in typical averaged seasonal conditions, a solution to this aspect has been evaluated. A dredging operation of the area has been hypothesized, with the use of both hydraulic and mechanical dredges and the consequent sediment transport has been studied, so that the impact of the operations on the aquatic environment could be considered. Tests have been carried on with MIKE 21 model, a professional software package for twodimensional free-surface flows. Results show that the most practicable solution is represented by the use of hydraulic dredging in summer conditions.
