Mathematical Models of the Underground Water Flow and Transport of Contaminants
Maryška, Jiří ; Mužák, Jiří ; Rozložník, Miroslav ; Tůma, Miroslav
Mathematical models of unsteady flow and transport in underground porous media. The governing equations in a compact form. They are discretized by Rothe method in time and by mixed-hybrid finite element method in space. Methods which provide an easy and robust way to solve both the flow and transport problems with mixtures of reacting contaminants. Basic components of such approach.

In the paper, we deal with the flood forecasting, in particular with determining the water flow as result of known precipitation. In the first part, we present several approaches how to express the water flow in the environment concluding underground flow, surface flow and channel flow in the ricer system (water runoff and flood routing). We discuss possibilities to simplify the shallow-water equations for slowly varying flow to either potential flow or advection-dispersion process. On the second part, we present results of two example models of 2D surface flow in the landscape, first based on the advection-dispersion representation of surface flow and the second mixed-hybrid FEM model based on potential flow approximation.
