Abstract
Recently there has been considerable interest in anomalous transport in porous media. An advection-dispersion equation (ADE) is widely used as governing equation of contaminant migration, however there have been a number of reports that ADE does not express observational and experimental data. This clear discrepancy is attributed to little knowledge about a mechanism of anomalous transport. The primary purpose of this investigation was to clarify the mechanism of anomalous transport analytically. In addition, a method, which predicts contaminant migration not only in homogeneous material but also in heterogeneous material, has developed by combining the clarified mechanism and streamline method. The result obtained from the developed method has agreed well with experimental results of this research.
