The project has two objectives:

1. to validate a computer program CONTAN for the simulation of contaminant migration and groundwater pollution

2. to use the same program for the simulation of case studies of contamination of groundwater

What are the results to date and the future of this work?

The program has been validated and case studies successfully analysed. In the next 6 to 9 months, more case studies will be analysed and the program capabilities extended to cover thermo-mechanical properties of soils. Later, the algorithm will be optimised for vector performance in order to increase the size of the problems it is capable of dealing with.

What computational techniques are used?

The boundary element method combined to the Laplace transform. Other algorithms used: complex-valued Gauss elimination for solving an algebraic system of equations, Talbot algorithm for converting Laplace values into time values.
