Flooding and Post-flooding Scenarios -Dynamics and Geochemistry

The geochemical and geohydraulic modeling of flooding processes is the scientific background for forecast and optimization of remediation. Basic principles are deduced from the dynamical description of flooding and post-flooding scenarios in different types of uranium mines. The time evolution is treated as a transition from dominant oxidation processes during flooding to long-term reduction processes influenced by reactive materials (organics, scrap iron). The spatial-time structure of the model depends on local conditions. The constructed models include advection, kinetics as well as equilibrium processes.
