Sekundarni naslov:	ǂA ǂcomparison of the MIKE 3 and PCFLOW3D models for hydrodynamic simulations inthe Gulf of Trieste
Sekundarni povzetek:	A comparison between the hydrodynamic simulations of the models MIKE 3 and PCFLOW3D in the Gulf of Trieste was performed. The model MIKE 3 was developed at the Danish Hydraulic Institute (DHI). It is used to simulate three-dimensional free-surface flow. At the Chair of Fluid Mechanics a similar model PCFLOW3D is being developed and practically used since 1985. This model is used to study processes in larger water bodies, such as lakes and seas, where the horizontal velocities are larger than vertical for an order of magnitude. The basic characteristics of both models are presented in this work. The input data and a comparison of the results of some simulations performed in the Gulf of Trieste with both models is further shown. Geometry and bathymetry data, temperature and salinity conditions in the Gulf of Trieste and at the Soĉa river mouth, wind velocity and direction as well as discharge and velocity of the River Soĉa were required for the simulations. Realistic seasonal conditions were simulated using different turbulence models. In the vicinity of the Soĉa river mouth a comparison of the results was performed also for a refined numerical grid. The agreement of results was better in winter conditions (bora wind), while simulations of tidal forcing and in summer conditions showed worse agreement of the results. The results of both models are comparable, despite relatively high discrepancies in some parts of the modelling domain. Minor differences in numerical schemes and turbulence models offered by both models and different input of boundary conditions, particularly at the open boundary and in the inflow cell, were found to be the main reasons of discrepancies.
