Numerical modeling of polloution distribution in the Nayban bay
In this study COHERENS which is a three-dimensional hydrodynamic model was employed in order to model and survey dispersion of pollution in Nayband bay. In this model Navier-Stokes equation, continunity equation and transport equations of salinity and temperature in 3-D are solved. Cartesian coordinate for the horizontal and sigma coordinate with five layers was used for the vertical profile. Monthly mean atmospheric parameters and 4 major tidal components (M2, S2, O1, and K1) of the bay were used as the inputs of the model. In this model, uniform grid of 79*100 was used. Once the model was adjusted and the data inserted, the model was run for the bay. Then tidal currents were validated with field observation which resulted in prediction of horizontal dispersion of pollution in different layers. The results showed that dispersion is highly affected by tidal currents. These results can be applied to predict dispersion of pollution in Nayband bay.
