| Popis: |
Groundwater flow near the Koeberg Nuclear Power Station was investigated by Stephenson in order to evaluate the extent of seawater intrusion around the foundations. In particular he studied the movement of the interface between fresh groundwater and seawater. For the purpose of such study it has been found necessary to determine the dispersion coefficient and confirm the velocity of fresh groundwater. This is carried out using131 I as tracer. Measurement of time distributions of tracer concentration in a series of boreholes permits the development of a mathematical model which appears to describe quite satisfactorily groundwater flow as well as intermixing in several layers. Dispersion across the interface has been anticipated and the dispersion coefficients for each separate layer and for the whole aquifer are determined from a fit of the model to the experimental data. |
