Survey of the first results provided by hydrogeological model of Latvia

In 2010–2012, scientists of Riga technical University have developed the hydrogeological model of Latvia (LAMO). In 2013, LAMO has been applied as a tool to implement in Latvia aims laid down by the European Union Water Framework Directive for sustainable use of water resources. The set of hydrogeological maps was prepared for updating of the water management plans for the river basin districts of Gauja, Daugava, Lielupe and Venta. For aquifers, distributions of groundwater heads and infiltration flows were mapped. In the maps of heads, directions of groundwater flows and contacts of aquifers with rivers were shown. By joining information, carried by the distributions for heads and infiltration flows, the special maps were created where isolines of heads and areas of groundwater discharge, recharge and transit were shown. Numerous geological profiles were provided. The profile represents the geological stratigraphy, isolines of groundwater head and directions of groundwater flows. Groundwater flow balances were obtained for the whole Latvia and for the river basin districts.
