| Abstract: |
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 Kelvin Wave theory as a 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. Performance of the hydrodynamic model for tidal
currents in the Persian Gulf is examined and tested using measurement results by imposing
tidal fluctuations to the main open boundary at the
Hurmoz strait. The spill analysis
model was setup using the flow field produced by
the hydrodynamic model to simulate an accidental oil spill 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.
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.
