... erosion in sand mud layers, we have developed a simulation of mud erosion by water flow in pore space. The simulation part with regard to water flow in pore space is based on LBM (Lattice Boltzmann Method). The sand particles are generated in a three-dimensional calculation area. The shear stress can...
