Abstract
Proposed is a computational algorithm for determination of surface currents under given wind conditions for prediction of oil slick trajectories in the Arabian Gulf. The algorithm interpolates a prespecified set of current velocities obtained from the three-dimensional hydrodynamic model of the Arabian Gulf. The three-dimensional hydrodynamic model of the Arabian Gulf computes surface currents for any given wind velocity. A database of surface current velocities for the selected wind conditions is created. The interpolation algorithm developed uses the database to compute the surface currents for various wind conditions. Numerical results indicate the feasibility of such an approach.
