Modeling Groundwater Flow in Unconfined Conditions of Variable Density Solutions in Dual-Porosity Media Using the GeRa Code

Flow of variable density solution in unconfined conditions and transport in dual-porosity media mathematical model is introduced. We show the application of the model to a real object which is a polygon of deep well liquid radioactive waste injection. Several assumptions are justified to simplify the model and it is discretized. The model is aimed at assessment of the role of density changes on the contaminant propagation dynamics within the polygon. The method of parallelization is described and the results of numerical experiments are presented herein.
