Accounting for Aquifer Heterogeneity in Solute Transport Modeling: A Case Study from the Macrodispersion Experiment (MADE) Site in Columbus, Mississippi

Field studies at well-instrumented sites have played a preeminent role in our efforts to better understand and characterize solute transport processes in geologic media. In particular, several field tracer tests conducted at well-known sites such as those in Borden, Canada (MacKay et al., 1986), Mobile, Alabama (Molz et al., 1986), Twin Lake,Minnesota (Killey andMoltyaner, 1988), CapeCod,Massachusetts (LeBlanc et al., 1991) and Columbus,Mississippi (Boggs et al., 1992) have provided new insights and extensive data sets for development and testing of transport theories and mathematical models.
