In 2010–2012, scientists of Riga Technical University have developed the hydrogeological model of Latvia (LAMO). In 2013, the first practical results have been provided by LAMO. The set of hydrogeological maps and groundwater flow balances has been prepared to update the current water management plan for the Gauja River basin district in Latvia. For aquifers, distributions of groundwater heads and infiltration flows have been prepared. In the maps of heads, directions of groundwater flows and connections of aquifers with rivers are shown. A set of geological profiles has been prepared. A profile represents geological stratigraphy, isolines of groundwater head and directions of groundwater flows. Groundwater flow balances have been prepared for the whole territory of Latvia and for the Gauja River basin district.
