The objective of this project is to study the theory and measurement of dispersion during miscible flow in heterogeneous nonuniform anisotropic porous media. An understanding of the dispersion phenomenon is necessary to predict flow of miscible fluids in non-homogeneous porous media. A significant literature review of dispersion in non-homogeneous porous media was accomplished. The continuum and statistical theories of flow in porous media were studied. A series of experiments in models of unconsolidated porous media were run to study the effects of heterogeneity, nonuniformity, and anisotropy on dispersion. The results have immediate practical applicates, especially in tracing of contaminents in surface and subsurface flow such as movement of pesticides, fertilizers, acid mine drainage, feed-lot waste, etc. through the soil.
