The hydrogeological model of Latvia will be established during 2010-2012. It will be used for management of drinking groundwater resources in order to implement standards of European Union Water Directives. The model will be created in environment of the commercial program Groundwater Vistas. It includes the broadly used software tools. The area to be(More)
The countries of the world and of the European Union are developing hydrogeological models (HM) where, by means of computer modelling, the information necessary for the groundwater management is obtained. In 1996, Riga Technical University (RTU), upon assignment of the former State Geological Survey, established regional HM REMO for the central part of(More)
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(More)
Since 1993, the team of the Environment Modelling Centre (EMC) of the Riga Technical University is being active in the field of developing methodologies and special software for creating hydrogeological models (HM). In this paper, these tools applied together with commercial ones are described, on the example of complicated HM created for the Noginsk(More)

In the Incukalns area (Latvia), the Devonian sandstone aquifer is heavily polluted by emissions of sulphur sludge pools. In 1998, a hydrogeological model (HM) for the place has been created and rough prognoses of contaminant migration in groundwater have been obtained. In 2004-2005, this model has been considerably improved in order to find the best methods(More)
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(More)
