In 2012, the hydrogeological model (HM) of Latvia has been established, by scientists of Riga Technical University. HM comprises the active groundwater zone that provides drinking water. The 3D-body of HM is approximated by the 95160125 size finite difference grid. Its plane approximation step is 500 metres and HM accounts for 25 geological layers.
The commercial software Groundwater Vistas (GV) is used, to run HM. The GV system contains tools used worldwide for hydrogeological modeling.
The most time consuming and troublesome part of establishing HM is to designate its geometry that is represented by thicknesses of geological layers composing the HM body. For HM of Latvia, most of these layers are outcropping. They are not continuous and, for this reason, they are not present everywhere on the area of HM
