Abstract
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.
Keywords: hydrogeological models; infiltration distributions; groundwater flow balance.
