Hydrogeological Model for Evaluating Groundwater Resources of the Central Region of Latvia
The paper explains design principles of the Regional Model (REMO) “Large Riga” created as a tool for investigating the groundwater reserves and the quality of the central part of Latvia. An original Geological Data Interpolation (GDI) routine has been developed to prepare a REMO input: a geometry and maps of permeability and boundary condition surfaces. Calibration algorithms for adjusting REMO parameters have been designed and successfully used. REMO has reached such a degree of credibility that it has been possible to make the first forecasts of the future development for the Riga groundwater system and to prepare an atlas of digital hydrogeological maps.
