Talajvíz térképek készítése matematikai modellezéssel 259 The behaviour of the groundwater table may be described by the extended form of the Boussinesq-equation with an additional member for the characterization of the vertical water motion. Components of this vertical water motion are: infiltration, evaporation, and horizontal flow (Fig. 1). The first two components are depending on the thickness of the aeriation zone and through this on the ground surface according to the Altovsky-Kovács relationship. The extended form of the Boussinesq-equation was solved on the computer by use of the DuFort-Frankel "VDM" algorithm. Coefficients of the extended Boussinesq-equation are calculated from the observation values of the groundwater observation wells, formulated as an inverse problem. By aid of the model hydroisohypsic maps of an area could be set up by the computer (Fig. 5) for mean water stages and highest water stages of the groundwater table.
