Sažetak
Analytical solution of sea water exchange process within some marina is very simple but excludes some important influences such as spatial position and shape of marina entrance, magnitude of sea currents outside of the marina and bottom slope inside the marina. 2D numerical model investigation are used to get insight into the relevance of those parameters on the rate of sea water exchange. Numerical simulation with different boundary conditions are made for cases with flat and inclined bottom, different ratio of entrance/marina width, trapezoidal, triangle and rectangular marina oblique, and diurnal sea levels elevation with amplitudes of 0, 25m and 0, 75m which are characteristic for Mediterranean sea. Values of used hydraulic parameters in numerical simulation such as bottom friction are valuated through the comparison of currents magnitudes within marina with values obtained on physical model investigation of some other authors.
