Modelling and Simulation of Ground Water Processes

To control and monitor pumping wells, drainage systems in mines and excavations pits, deposits and industrial or agriculture contaminants, it is necessary to know the processes in the soil and groundwater zone. There are physical, chemical and/or biological processes. The physical processes are described mathematically by a system of partial differential equations (PDEs). The groundwater flow described by the heat-conduction equation and the transport of substances by the convection-diffusion equation. For a few of the simplified groundwater relationships one can use simple equations. For the decision support of the water experts and the simulation of a few important processes in the soil and groundwater zone a Computer Aided Engineering (CAE)-Groundwater system is developed at the Dresden University of Technology.
