Sažetak
The possibility of maintaining the sea quality in closed basins, most often by using artificially shaped closed spaces, e.g. marines or small harbours, linked to the sea by a small opening, is being discussed in this paper. By introducing a jet of fresh sea water into the basin, the water is mixed and partially forced out of the confined space thus reducing the concentration of harmful components. A possibility of basin cleansing by a large propeller device and by appropriate jet nozzle system is examined on a hydraulic physical model of a simple geometry marina. The result obtained to confirm the advantages of a jet system and the quality of each tested system is determined by a mixed factor. It is obvious that the location of the circulation system is of great importance. Therefore the optimal location with regard to geometry is indicated.
