The hydrodynamic is solved in ´ advance and includes a barotropic model for calculating tides and a reduced gravity model for the average circulation. Dispersion is calculated using particle-tracking methods. Turbu lent diffusion and specific processes for contaminants (for instance decay, biodegradation or oil evaporation) are simulated by Monte Carlo techniques. Computed tide elevations and currents are in agreement with observations. Also, the reduced gravity model reproduces the main characteristics of the residual circulation in the area (namely the western Alboran´ gyre, WAG, and the coastal circulation mode). Some examples of dispersion calculations are given. The calculated transit time of contaminants over the Alboran Sea is in agree- ´ ment with that obtained from float experiments. The model may be used to support the decision-making process after a pollutant release in the area. |
