Abstract
The transport of contaminants has been a problematic issue for many years, mainly due to the adverse impact of the contaminants on the quality of groundwater. In order to analyse this, this study has developed a prediction model that allows the early detection of possible contamination. Firstly, the paper introduces the concept of the modelling of contamination transport through a soil matrix. Then it presents a two-dimensional Convection-Dispersion Equation (CDE) for contaminant transport in a soil matrix. This includes the investigation of different reaction coefficients and time-dependent inlet boundary conditions, from which a numerical solution is derived. The study also verifies recent previous work in this area through the use of numerical programming. The results for soil contamination in two dimensions are presented in this research.
Highlights
Contamination in soil may include different kinds of waste such as bacterial, chemical or radioactive waste
The modelled monstrated the capacity to cover the results of 1D modelling in the verification step and was extended to the 2D domain
The numerical modelling of the 1D model alone, with a new approach to obtain better and quicker results compared to the analytical approach done by Gao et al [1], makes a significant impact on the fieldof contaminant transport
Summary
Contamination in soil may include different kinds of waste such as bacterial, chemical or radioactive waste. Gao et al [1] considered a 1D model of contaminant transport in a soil matrix.
