Estimation of Two Dimensional Solute Transport Parameters Using Tracing Experiment Data

R. Derakhshani and A. Bazregar

Abstract:
The effective solute transport parameters, longitudinal dispersivity (αx), transversal dispersivity (αy) and retardation factor (R) for a two-dimensional plume are estimated using time-concentration data of a sampling borehole through which the plume passes. The plume was produced by injection of 2 kg Uranine (Sodiumfluorescien; Color Index: 45350) in a borehole in uniform groundwater flow. Two-dimensional analytic equation of solute transport in a uniform groundwater flow was used to estimate the parameters. The results were compared with one well method of dispersivity estimation. A time-concentration curve was drawn using estimated parameters and compared with the observed time-concentration curve. Comparison shows the accuracy of the estimated parameters obtained by the former method. Based on the estimated parameters and the two-dimensional analytic equation the movement of the plume is predictable at any arbitrary time after injection for the study area. Based on the estimated parameters and the two-dimensional analytic equation the movement of the plume is predicted at 85 days after injection for the study area, where as it is shown in this study the predictable and observed concentration curve are exactly equal.
