| Abstract | Two experimental approaches were used to examine transport in saturated porous media. One design, the box experiment, allowed two-dimensional sampling of the solute plume. The more traditional column design was one-dimensional with sample collection only at the effluent end. A total of three box and two column experiments were conducted. The method of moments was used to analyze plume behavior in both experiments. Comparison between the experiments were made using the moments. For similar porous materials the same retardation was observed despite an order of magnitude different in velocities. Data from the one-dimensional column experiments were used to estimate dispersivities that were used to predict the behavior in the multidimensional box experiment. Results indicated that velocity information from the box experiment was needed in order to attain an adequate prediction of its response. 8 refs., 9 figs., 12 tabs. |
