Abstract
This study presents an application of the random cascade model to the evaluation of the transport phenomenon in soil. Dye tracer tests were carried out and dye staining patterns were digitized for the analysis. The dye staining pattern showed heterogeneous response in all of experimental scales, 0.25, 0.50 and 1.00 m. The random cascade model was applied to the dye infiltration patterns and heterogeneous dye infiltration patterns were well described. The lognormal distribution was used to the random cascade generator and conformability result was shown. Maximum dye infiltration depth in case of each experiment was proportional to the experimental scale. Estimated parameter of the random cascade model, σ (standard deviation) showed a tendency of the scale dependency.
