Abstract In the work SRT Lattice Boltzmann model in CFD are considered. With their help numerical experiments for real basins are made. At numerical modeling used D3Q19 model which has been modified for not cubic grids, that is with prevalence of one of step in space. SRT models have shown high speed of calculations and simplicity of using in numerical computations.
