EXPERIMENTAL STUDY OF GROUNDWATER CONTAMINANT TRANSPORT AND DETERMINATION OF LONGITUDINAL DISPERSIVITY
Abstract
Groundwater is the safest and most important source of available freshwater. However, it is threatened by pollution arising from various activities. In this study the contaminant transport in homogeneous medium is investigated by means of an experimental set-up designed for the hydrologic cycle available in Hydraulics Laboratory. The experiments are carried out in the physical aquifer chamber 2 m long, 1 m wide and 0.10 m high. The piezometer tubes and observation wells are placed at the bottom of the chamber longitudinally and transversally. NaCl solution which represents contaminant is injected from a well instantaneously, as a point source. Electrical Conductivity (EC) values of the water are measured by using probes placed in the observation wells. Measurements are taken at specific time interval. The NaCl concentrations of the samples are determined indirectly by converting these measured EC values to concentration values by means of the calibration curve generated at the
beginning of the experiments. Consequently, the longitudinal dispersivity of the porous medium was determined by solving the one dimensional advective-dispersive equation.
