Abstract: | Summary An alternative method has been proposed and performed to determine the relevant soil parameters - such as dispersitivity and
distribution coefficient - related to the use of a tract of land for a toxic waste repository. The method makes use of radioactive
tracers and a geotechnical centrifuge to accelerate relevant migration processes. A few soil types and tracers have been employed.
Experimental data were then compared to those predicted by the advection-dispersion equation. Preliminary results indicate
that this alternative method is useful for the determination of the above parameters, especially when fine soils are involved. |
