Oil spill simulation from the marjan offshore oil field

The oil spill simulation model GULFSLIK III is applied to simulate an oil spill in the Marjan oil field, an important offshore field in the Arabian Gulf. The model incorporates several new changes over previous versions, including a surface spreading formula developed from measurements of experimental spills in the gulf. Other features are a variable release rate for the spilled oil, a two-component evaporation model, and dispersion in the vertical and horizontal directions. The currents in the region are simulated using a multilayer hydro-dynamical model, in which the driving forces include wind stress and density gradients produced by evaporation, fresh water inflow, and radiative heat transfer.
