| Abstract |
Many hydrologists have observed that dispersion coefficients, when measured in the field, turn out to be scale-dependent. Recently, Guven, et al., (1983) presented a study which contains a basis for understanding the phenomenon of scale-dependent dispersion within a deterministic framework. The results of that study are used as a basis for defining a scale-dependent macro-dispersion coefficient for unidirectional flow in a stratified aquifer. The study and previous studies show that the primary physical mechanism that causes spreading of a solute near the source is different advection rates at different elevations in the aquifer. |
