In 2014-2018, scientists of Riga Technical University (RTU) have updated the hydrogeological model (HM) of Latvia. Its current version LAMO4 simulates the steady state average groundwater regimes. The commercial program ?Groundwater Vistas 6? (GV) is used for running LAMO4. Unfortunately, the GV graphical programs cannot provide correct profiles on hydrogeological data that are obtained by HM. In 2014, the first RTU results were reported on creating profiles for groundwater heads and infiltration. Since 2014, the ...

Hydrogeologists are interested in borders that separate the groundwater recharge, transit, discharge (RTD) areas. Unfortunately, no good method exists for finding them. In the course of using the hydrogeological model (HM) of Latvia (LAMO) scientists of Riga Technical University have developed the new method that generalizes the RTD concept and gives locations of the borders. LAMO is run by the commercial program Groundwater Vistas (GV). The GV program provides the velocities vz for the vertical and vx, vy for the...
