Methods Used to Develop Hydrogeological Model of Latvia

In 2010-2012, the hydrogeological model (HM) of Latvia LAMO was established by scientists of Riga Technical University. The model will be applied for management of water resources of Latvia. The 3D-body of LAMO is approximated by the 95160125 size finite difference grid. Its plane approximation step is 500 metres and LAMO accounts for 25 geological layers that represent the active groundwater zone of the country. The commercial program Groundwater Vistas (GV) is used for running LAMO. GV includes the MODFLOW program that is worldwide applied for development of HM. Novel methods were used to develop LAMO. They took part in performing the following tasks: creating geometry of HM; arrangement of various boundary conditions (digital terrain map, hydrographical network, infiltration flow, conditions on the HM shell surface); calibration process of HM

In 2010-2012, the hydrogeological model (HM) of Latvia LAMO was established by scientists of Riga Technical University (RTU). The commercial program Groundwater Vistas (GV) is used for running LAMO. Efficient methods were used for creating geometry of HM, for arrangement of various boundary conditions (digital terrain map, hydrographical network, infiltration flow, conditions on the HM shell surface) and to calibrate HM. Their appliance considerably improved quality of HM and reduced time needed to create LAMO.
