Abstract:
The numerical modeling of spatio-temporal evolution of lagoon has an important role in predicting
the behaviour of these systems. Knowing the concentration of the pollutant field distribution in time and space
contributes significantly to the prediction of exceptional phenomena. The purpose of this paper is to simulate
the transport and dispersion of salt at Nokoue Lake. To this end, the 2D hydrodynamic model SMS (Surface
Water Modeling System) has been used. Results showed that in flood period the freshwater inflows produce
a net seaward transport, while in low water period the tides lead to periodic seaward and landward transport.
The developed numerical model is useful for predicting pollutants transport in this system, for water quality
management of the Nokoue Lake, and therefore, fight against eutrophication.
