Comparative analysis of classical models (MARS3D, AZOV3D) and lattice Boltzmann models for shallow water hydrodynamics computations

Different numerical approaches of hydrodynamics of shallow water basins are considered and compared. Two approaches are developped in TIT-Russia: one of them is classical and based on numerical solution of the Navier-Stokes equations by Pressure-Correction method, another (developed several years ago) is  based on the solution of the Lattice Boltzmann kinetic equation. The comparative analysis of these two approaches with MARS3D is performed for a shallow water basin example: «Etang de Berre»

Turbulent mixing and stable current structures for Etang de Berre

Parameterization of coefficient of vertical turbulent exchange plays important role in the hydrodynamics of shallow water basin. Relevant parameters are determined on the basis of ADCP in situ experiments. They are implemented in Azov3D package developed at TIT-Russia. They are used to determine the currents in shallow water basins: Etang de Berre, Etang de Bolmon and Azov Sea. Comparison are performed with currents computed using another well known package (MARS3D)
