Steady-state flow and tracer transport between an injection well and a pumping we in a heterogeneous confined aquifer were investigated with numerical modeling. Calculation of transport was based on the advective model for heterogeneous aquifers. Dispersion was assumed to be controlled by microscale velocity variation. An effective parameter of dispersion evaluated on the breakthrough curves was defined to account for the influences of heterogeneity. Breakthrough curves were calculated by using numerical modeling of transport in a strongly heterogeneous aquifer with spatial heterogeneous transmissivity fields. The results of modeling were processed by comparison with analytical solutions of doublet systems to obtain the effective parameters. A special solution was developed for advective transport in aquifers with a layered structure. Examples of real field heterogeneity were given to show its influence on breakthrough cures and the resulting impact on the effective macroscopic parameters.
