Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="PlaceName"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="PlaceType"> <span style="color: rgb(20, 19, 20);" lang="EN-GB">Oil spill simulation due to the wind and wave fields and tidal currents in the Persian Gulf by solution of the hydrodynamics and convection-diffusion equations have been presumed. Model consists of algorithms describing the processes of advection, surface spreading, horizontal and vertical dispersion, evaporation and emulsification. Tidal constituents have been obtained from co-tidal charts. Sea level and surface velocity has been determined by <span style="color: rgb(20, 19, 20);">Kelvin Wave theory as a <span style="color: rgb(20, 19, 20);">new hydrodynamic calibration tool to prepare flow pattern and successful speed-up procedure. Artificial wind field has been generated in order to prepare wind field time series in the accident interval. <span style="color: rgb(20, 19, 20);">Performance of the hydrodynamic model for tidal currents in the Persian Gulf is examined <span style="color: rgb(20, 19, 20);">and tested using measurement results by imposing tidal fluctuations to the main open boundary <span style="color: rgb(20, 19, 20);">at the Hurmoz strait. The <span style="color: rgb(20, 19, 20);">spill analysis model <span style="color: rgb(20, 19, 20);">was setup using the flow field produced by the hydrodynamic model to simulate an accidental oil spill<span style="color: rgb(20, 19, 20);"> and its performance was further validated using the existing data at the Kish Island. Langevin equation for vertical dispersion has been calibrated for the considered domain. <span style="color: rgb(20, 19, 20);">Comparison of the actual and simulated oil spill drift was found reasonably acceptable allowing for application in risk assessment analysis in the northern part of the Iranian waters. </span></span></span></span></span></span></span></span></span></span></smarttagtype></smarttagtype></smarttagtype>
