摘要
A simple capillary bundle model was evaluated for describing solute dispersion in two well-aggregated soils of Hawaii. The model enables the use of pore-water velocity distribution rather than an average pore-water velocity. The pore-size distribution was calculated from the soil water characteristic data. The position and relative shape of the break-through curves calculated by the capillary bundle model was dependent more on the pore-water velocity distribution than on dispersion owing to mixing within a pore.
