The objective of this thesis was to implement a new module to the DRUtES model code, which allows to calculate coupled transport of moisture, temperature and miscible substance in a variably saturated porous media. The main part of the practical phase of the thesis was to implement appropriate constitutive relationships describing a coupled transport to the Galerkin finite elements scheme previously implemented in the DRUtES model. Besides this, a corresponding configuration files were made to assign parameters of the model into program data structures as well as a little bit of other programming work elsewhere in the code. Numerical solution of each transport equation was compared with its analytical solution. 1D moisture transport with the Philips semi-analytic solution of diffusive form of Richards equation. 2D temperature and miscible substance transport with an analytical solution of advection-dispersion equation. This comparisons suggested that the implementation was correct. The coupling of these processes was compared with a reference numerical solution. In this case was the fitness of results assessed in more qualitative manner with a literature. Before use of this coupled model to solve a real world problem, I would recommend to make a similar assessment with the real data.
