An Oil Spill Model on the Kelvin Wave Theory and Artificial Wind Field for the Persian Gulf

Abbstract :

Oil spill simulation due to the wind and wave fields and fidal currents in the Persian Gulf by solution of the hydrodynamics and convection-diffusion equations have been presumed. Model consists of algorithms describing the process of advection, surface spreadinf, horizontal and vertical dispersion, evaporation and emulsification . Tidal consistuents have been obtained from co-tidal charts. Sea level and surface velocity has been determined by kelvin wave theory as a new hydrodynamic calibration tool to prepare flow pattern and sucessfujl speed-up procedure. artificial wind field has been generated in order to prepare wind field time series in the accident interval . Performance of the hydrodynamic model for tidal currents in the Persian Gulf is examined and tested using measurement results by flow field producedby the hydrodynamic model to simulate an accidental oil spill and its performance was further validated using the existing data at the Kish Island Lengevin equation for vertical dispersion has been calibrated for the considered domain. Comparison of 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.
