TWO-PHASE MODEL OF FILTRATION OF HEAVY LIQUID CONTAMINANT IN LAYERED AQUIFER
SINOPSIS
The filtration process of a heavy liquid contaminant permeating into a layered sloping inhomogeneous freshwater reservoir through parts of its boundary in the presence of infiltration from the top is studied by the mathematical and computer simulations. Two typical situations of the formation and evolving of the contamination field are considered. In the first one of them the contamination takes place at the reservoir inlet (e.g., as a result of seawater intrusion) and in the second one the liquid contaminant enters the reservoir through a part of its roof. Mathematical model is developed within the framework of the two-phase filtration theory for immiscible liquids. The influence of the reservoir structure, strata inclination, low-permeable inclusions and impenetrable barriers, intensity of the infiltration flux and its seasonal fluctuations on the heavy contaminant distribution is studied by computational experiments.
