The countries of the world and of European Union are developing hydrogeological models (HM) where by means of computer modeling, the information necessary for groundwater management is obtained. In 2012, the Riga Technical University (RTU) has finished establishing of HM that covers the whole territory of Latvia and border areas of neighboring countries. HM accounts for 25 geological layers of the active groundwater zone (till the Narva D2nr regional aquitard) that is being used as a source for providing drinking water. The 3D-body of HM is represented by 95160125 finite difference grid. which plane approximation step is 500 meters. To ensure compatibility with models of other countries, the commercial program Groundwater Vistas (GV) is used for running HM. GV contains software tools applied for groundwater modeling worldwide.
HM is a part of the Latvian Shared Environmental Information System. It is supported by the Latvian Environment, Geology and Meteorology centre. HM comprises geological and hydrogeological information provided by the centre.
