【 摘 要 】
Project Objective: (1) Provide an improved understanding of how preferential vertical and lateral flow, and the formation of immobile water influence the transport of radionuclides and toxic metals in heterogeneous, laminated sediments. (2) Quantify the rates and mechanisms of radionuclide and toxic metal interaction with the solid phase under various hydrologic conditions. (3) Provide new insights into how physical and mineralogical heterogeneities (e.g. stratification, pore regime connectivity, mineral composition along flowpaths) influence contaminant retardation and the degree of geochemical nonequilibrium during transport.
