effect of vertically decreasing macropore fractions on simulations of non-equilibrium solute transport

The effects of a depth-decreasing macropore fraction and the corresponding decrease in the diffusive mass-transfer coefficient for solute exchange between soil matrix and macropore regions were simulated for a hypothetical, one-dimensional, mobile-immobile, transport domain. These effects are illust...
