The ground water pollution problem is being solved in most cases by finite
difference methods and in other cases by finite element methods.
The DRM is
now applied to such problem.
The governing differential equation (transport
equation) including convection terms and sources or sinks are stated together
with boundary conditions.
For easier adaptation of the programs published by
Partridge, Brebblia and Wrobel (1992) and to get rid of singularities, the
sources (or sinks) are substituted by a source strength across a small internal
The first application refers to the unidirectional flow with prescribed
concentration on one boundary and zero-dispersive-flux on the other
The results compare...
