AB: Lattice-Boltzmann (LB) modeling has found increasing application in hydrology. In this paper, we present a general LB modeling approach for multiphase-multicomponent porous medium systems. Further, we present two examples in which we use LB modeling to better understand macroscale behavior of such systems. In the first example, we investigate the formation of traveling bands of chemotactic bacteria and its potential application to the remediation of contaminated groundwater. In the second example, we demonstrate how LB modeling can be used to derive mass-transfer correlations for the dissolution of nonaqueous phase liquids (NAPLs).
