Abstract or Summary
  • A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all construction and repair materials tested as part of this study sorption was the dominant removal mechanism. This thesis presents the development of a simple algorithm used for the solution of the advection-dispersion equation incorporating advection, reversible equilibrium sorption, dispersion, and biodegradation. Algorithm results are compared to analytical solutions of the advection-dispersion equation, to column studies conducted as part of this research project, and to results from column studies of cadmium and pesticide (picloram) transport conducted by other researchers.
