In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by the scientists of Riga Technical University (RTU). LAMO comprises geological and hydrogeological data provided by the Latvian Environment, Geology and Meteorology Centre (LEGMC) for the active groundwater zone of Latvia. In 2013–2015, LAMO was notably upgraded. The density of hydrographical network (rivers, lakes) was increased, cuttings of river valleys into primary geological layers were done, plane approximation step was decreased, hydraulic conductivity distributions of layers were refined by creating more reliable permeability maps. In the paper, methods of obtaining these maps are described.
