The hydrogeological model of Latvia will be established during 2010-2012. It will be used for management of drinking groundwater resources in order to implement standards of European Union Water Directives. The model will be created in environment of the commercial program Groundwater Vistas. It includes the broadly used software tools. The area to be modeled is represented by 95160125 finite difference grid, which plane approximation step is 500 metres. Novel methods and software tools will be applied to create the highly complicated model: the map of the ground surface elevations will serve as the piezometric boundary condition for obtaining distribution of infiltration; for creating digital maps of the model initial data, original software tools of data interpolation will be used; in the initial phase of the model establishment the actual geometry of a model may not be applied.
