Abstract

The mathematical model for coastal zones management requires the elaboration of two numerical models. The first of them (circulation model) allows us to describe the state of currents and tide in the estuary, providing the data necessary for the second model application (dispersion model). This mathematical model will provide the concentrations of the polluting particles, dissolved in water. In this paper a numerical model has been developed, based on the finite elements method, to forecast water movement and pollution in bays and estuaries. The response of the system is obtained as the solution of the continuity, moment and dispersion equations. The developed model is based on a Galerkin formulation of the 2-D equations of the hydrodynamics and dispersion of the estuaries, with spati
