Computational modelling of tidal effect on wastewater dispersion in coastal bays,case of Tangier's bay (Morocco)

This study is focused on numerical simulation of the process of coastal pollution by wastewater in the bay of tangier. the numerical model is based on shallow water equation used for the hydrodynamic and equation of advection-diffusion for describes the wastewater assimilated like passive pollutant. the obtained model is resolved using an unstructured triangular finite volume method. the found results show that: (i) the tidal flows have a direct effects on wastewater dispersion that can used to control its evacuation out of bay (ii) the numerical model used can modelling domains that have more complicated geometry and bathymetry,this in a large time scale.
