MICHALAK, J. & LEÊNIAK, P.M. 2003. Features and coverages in hydrogeological information. Acta Geologica Polonica, 53 (3), 247-255. Warszawa. In recording hydrogeological information in computer systems (databases, GIS), it became necessary to manipulate them in a consistent and efficient way. The correct functioning of these systems depends principally on the applied data models, which should ...

Design and construction of hydrogeological information systems is now a necessity. For proper functionality of these systems, it is necessary to create them in accordance with widely accepted international standards regarding geospatial information. Geomatics research tools allow for creation of basic models of hydrogeological data, consistent with these standards. The models can be based upon ...

[1] Using numerical models, we evaluate hydrogeological regime changes in high-latitude river basins under conditions of ground surface warming. These models describe transient heatand fluid flow coupled to the hydrogeological impacts of phase-changes from ice to liquid water. We consider an idealized unconsolidated sedimentary aquifer system in which groundwater flow is driven by topography, r...

[1] Defining rational and effective hydrogeological data acquisition strategies is of crucial importance as such efforts are always resource limited. Usually, strategies are developed with the goal of reducing uncertainty, but less often they are developed in the context of their impacts on uncertainty. This paper presents an approach for determining site characterization needs on the basis of ...

Q.3-A clear understanding of the hydrogeological setting seems a fundamental place to start; is this possible in the absence of a team groundwater specialist?

Detailed knowledge of the subsurface is a prerequisite for the planning of effective site remediation. Conventional investigation of contaminated sites is based mainly on observations from wells. However, practical limitations on the number of wells mean that characterization of the subsurface based on borehole data alone leads to uncertainties in determining the hydrogeological parameters and ...

Uncertainty in conceptual model structure and in environmental data is of essential interest when dealing with uncertainty in water resources management. To make quantification of uncertainty possible is it necessary to identify and characterise the uncertainty in geological and hydrogeological data. This paper discusses a range of available techniques to describe the uncertainty related to geo...

In this work we present a study about cognitive agents that have to learn how their different information sources can be more or less trustworthy in different situations and with respect to different hydrogeological phenomena. We introduced an ad-hoc Bayesian trust model that we created and used in the simulations. We also describe the realized platform that can be manipulated in order to shape...

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) wa...

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 used commercial program Groundwater Vis...
