On the Applicability of Analytical Solutions of the Transport Equation for the Migration of Substances in Groundwater-Bearing Horizons

Using experimental data from indicator pump tests, various theoretical migration models for radionuclides in groundwater-bearing horizons were considered. The model parameters necessary for these considerations, especially migration velocity and dis-persivity, were obtained by statistical analysis of experimental data. These results show that pulse-like indicator injection best measured values for the model of instantaneous injection in indicator-free flowing groundwater in an infinite strata.
