| Zusammenfassung |
| Analytical and numerical solutions are obtained for
dispersion of pollutants along unsteady groundwater flow in a longitudinal direction
through semi-infinite aquifers the permeability of which is either uniform or varies with
position. Sources of pollution are both a concentrated point input at the origin and a
spatially distributed background source. One expression chosen to represent the seasonal
pattern of the time dependent velocity is sinusoidal behaviour over a year. The solutions
obtained predict the time and distance from the location at which an input concentration
is introduced at which the pollution concentration becomes harmless. Also, the time period
for rehabilitating a polluted aquifer for human use can also be assessed. |
