Abstract
Groundwater circulation wells (GCW) are in-situ decontamination technology, it means there is no need to pump groundwater above ground surface. That is the reason why we have to study processes which occur underground in detail.
For this purpose this thesis article uses numerical modelling based on quantity of field measurements. The numerical modelling was used to examine the effect of GCW on natural groundwater flow and, otherwise, to determine the effect of hydraulic and well parameters on decontamination quality.
Two types of models were used to examine the groundwater flow in the vicinity of the GCW - a simple model of GCW in homogenous izotropic environment and a complex numerical model of groundwater flow in pilot locality (Velká Hleďsebe). In both cases it appears that the hydraulic parameters have the major effect on contamination quality.
