The paper deals with a 2D mathematical model, which describes the groundwater temperature. Such a model is an interesting alternative for 3D equations, which re-quire much more additional information (i.e. shape and characteristics of the area, initial and boundary conditions) than 2D equations. In the first part of the paper the equations of energy conservation for two main versions of a 2D model (i.e. for a confined and for an unconfined area) were derived. Special attention was paid to two kinds of heat-transfer processes, viz. micro-dispersion, caused by pore-space averaging of the temperature and velocity, and macro-dispersion, due to averaging along the water-layer depth. The analysis of the thermal conditions in the region of the Kozienice electric-power-plant was presented, as an example of the model application.
