Sekundarni naslov: Calculation of hydrodynamic quantities in the Gulf of Trieste due to changing meteorological parameters
Sekundarni povzetek: In the thesis, we wanted to find time-averaged wind fields over the Gulf of Trieste, which still give satisfactory results in the flow simulations. Simulations of circulation with the PCFLOW3D model were performed using the reference wind fields at hourly intervals and time-averaged wind field over 3, 6, 12 and 24 hours. The results of the simulation were compared in the form of vector images of the wind speed at the selected time and circulation images within the layers at the depths 0.5 meters and 10.5 meters. In the surface layer, the discrepancies between the circulation caused by reference wind fields and the averaged wind fields are greater than at a depth of 10.5 meters, because the effect of the wind on the surface layer is significantly larger. A useful match was achieved using 3 and 6 hours averaging. Therefore, wind data from meteorological models in the interval of 6 hours or less can be recommended for normal short-term simulations of pollutant transport and dispersion.

Povzetek (ePrints): V diplomski nalogi smo želeli poiskati časovno povprečenje vetra nad Tržaškim zalivom, ki še daje zadovoljive rezultate pri simulaciji tokov. Izvedli smo simulacije hidrodinamike z modelom PCFLOW3D z referenčnimi vetrovnimi polji v enournih časovnih intervalih in s časovno povprečenimi vetrovnimi polji preko 3, 6, 12 in 24 ur. Nato smo med seboj primerjali rezultate simulacij v obliki vektorskih slik hitrosti vetra v izbrani uri ter tokovnih slik slojev na globini 0,5 metra in 10,5 metra. V površinskem sloju so bila odstopanja med referenčnimi hitrostmi in hitrostmi zaradi povprečenega vetra večja, kot na globini 10,5 metra, ker je vpliv vetra na površini večji. Uporabno ujemanje smo dosegli pri 3 in 6 urnem povprečenju, zato tudi priporočamo za običajne kratkoročne simulacije transporta onesnažil podajanje vetra iz meteoroloških modelov v časovni resoluciji 6 ur ali manj.
