| | Summary: |
| | This paper presents a one-dimensional numerical pollutant transport model.
In order to achieve better accuracy the equation was solved using the Holly -Preissmann
method for advection, and the Crank-Nicholson scheme for diffusion. The results gained
by solving the complete transport equation using the differnt methods were anlysied and
compared. After that the equation was modified for one-dimensional pollutant transport
in groundwater, where the pollutant is subject to biological/chemical degradation. The
model was applied to an example using the ammonium ion NH4+
as the pollutan. |
