Sažetak
3D numerical model analyses the impact of the breakwater culvert on the exchange between the sea waters of the marina and the open sea of the northern and southern Adriatic. The breakwater in the model analysis was treated as a vertical impervious barrier. In the analysis the hypothetical layout configuration of the marina (position inputs and width of the entrance to the marina, proportion of the length and width of the marina) varied. Sea currents in the model domain was generated by using non-stationary boundary conditions in the form of time series of sea levels based on seven constituents of the tidal signal. Wind-driven forcing is not taken into analysis. The research results show that the breakwater culvert in the analysed conditions reduces the e-folding time for exchange between the sea waters of the marina and the open sea average to 88%. The construction of breakwater culvert increases exchange between the sea waters when three breakwater culverts are positioned in the marina with an entrance in the side breakwater.
