Optimization of Port of Split by Numerical and Physical Modeling

The Split city port is a historical multifunctional port on the eastern coast of the Adriatic Sea, its size being 1.3 sq.km. The port is inadequately protected from waves, causing overflow and mooring problems. New requirements for improved operational efficiency and higher capacities within the aquatory impose the need of construction of new waterfronts and improved wave protection. The present wave situation in the port for critical wind directions and selected wave spectra was investigated by means of the physical model, at the scale of 1:50, and good agreement was achieved with phenomena observed in the port. Mathematical modeling of the same problem was carried out by numerical models Mike 21/BW and Telemac, generally showing good agreement. All models were used for successive investigation of five modifications in separate parts of the port, including new waterfronts and extensions of breakwaters. Critical waves selected for agitation of the port basin were the waves of 5-year return period from SE (HS = 2.9 m) and S (HS = 2.3 m) for which the JONSWAP spectrum was used. The results of physical and mathematical modeling for characteristic points in the port and in the vicinity of new waterfronts were subjected to comparison. The results show high sensitivity of construction of new vertical waterfronts to increasing wave heights in the present situation. Therefore it is necessary to construct them in the form of dissipation chambers, and to extend the existing breakwaters which will, according to the results of modeling, provide considerably more favorable situation compared to the present.
