Upgrading of the Hydrogeological Model of Latvia

In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by scientists of Riga Technical University (RTU). The model generalizes geological and hydrogeological information accumulated by the Latvian Environment, Geology and Meteorology Center (LEGMC). LAMO simulates the active groundwater zone that provides drinking water. The worldwide used commercial program Groundwater Vistas is applied for running LAMO. In 2013 – 2014, LAMO has been considerably upgraded and, presently, three successive versions (LAMO1, LAMO2, LAMO3) can be marked. The main innovations are considered that have converted the basic LAMO1 into the more advanced LAMO3 version that accounts for larger amount of real hydrographical and geological field data
