- This paper focuses on illustrating how the Boltzmann theory can be used to formulate numerical algorithms for three-dimensional shallow water equations. The paper begins by showing that the classical three-dimensional shallow water equations are obtainable from the moments of the Boltzmann Bhatnagar-Gross-Krook (BGK) equation. This connection is then exploited to formulate a three-dimensional finite volume for shallow flows in which the fluxes are obtained on the basis of the BGK equation. The resulting scheme is illustrated using a variety of surface water problems. The advantages of using the Boltzmann-based to formulate numerical algorithms for surface water flows are summarized.
