The core equation in the LBM turns out to be a special discrete form of the continuum Boltzmann equation, leading it to b

Introduction,iven. This includes the origin of the lattice Boltzmann method, its advantages and the purpose of the book. Chapter 2 describes the governing equations for general fluid flows and subgrid-scale stress model for turbulence modelling. Based on these, the shallow water equations are derived in detail.

Lattice Boltzmann Method,sists of three basic tasks: lattice Boltzmann equation, lattice pattern and local equilibrium distribution function. The former two are standard, which is the same for fluid flows. The latter determines what flow equations are solved by the lattice Boltzmann model, which is often derived for certain

In order to solve shallow water flow problems by use of either LABSWE or LABSWE., suitable boundary conditions must be provided. Therefore, this chapter firstly

Introduction,ture of the scheme is analyzed and compared with available schemes. Also, the . (.-property) as a basic criterion for a numerical scheme is introduced. Chapter 5 describes a lattice Boltzmann model for the shallow water equations with turbulence modelling (LABSWE.) by incorporating the subgrid-scale
