Sažetak
With growing anthropogenic activity at the coast, the seawater quality is under threat. Manmade semi-enclosed basins like harbours and marinas are focal points where the pressure is the greatest, due to its reduced ability of seawater exchange with the external seawater and therefore undesirable pollution accumulation. Flushing culverts imbedded inside breakwaters provide a viable cost-effective solution in order to improve the seawater exchange, most commonly used in small tidal range areas. With the intention of evaluating the contribution of flushing culverts to water exchange, field measurements have been conducted in ACI marina Opatija, Croatia during summer and winter periods. The influence of freshwater sources present during winter, tidal oscillations and wind action are being analysed in this paper. Wind energy has been utilized as a reference value for wind action impact on the flow through the flushing culvert. It has been observed that in addition to a greater wind velocity, a smaller angle between the direction of the wind and the direction of the flushing culvert provides greater seawater exchange through the flushing culvert.
