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 be based on commonly accepted international standards of geospatial information. This is particularly important in the case of interoperability of different systems, for example a system simulating hydrogeological processes and the hydrogeological geospatial database system. The research tools of geomatics allow the construction of data models of such systems conformable to these standards. However, in the definition of such a model several ontological and semantic inconsistencies arise. Two examples are taken for consideration: hydrogeological feature and coverage. These terms are frequently applied improperly to cases of geospatial information. Definition of these terms in a hydrogeological context will prevent ambiguities in formulating models of hydrogeological data.

Geomatics in hydrogeology
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 ...
متن کاملInvestigation of folding lateral growth using study of erosional processes and geomorphological and hydrogeological indices (Case study: Khaviz oilfield)
Recognition of growth pattern and folding mechanism in the fold-thrust belts with hydrocarbon resources is important in exploration and development planning of oilfields. As the processes of tectonics, erosion, and geomorphology impact on each other, therefore, the investigation of a process, one can obtain information about the other process. In this research the tectonic process of transverse...
متن کاملHow to Manage the Information Sources' Trustworthiness in a Scenario of Hydrogeological Risks
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...
متن کاملCoastal hydrogeological system of Mar Piccolo (Taranto, Italy).
The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment. Because of the karstic features, the main continental water inflow is from groundwater discharge. The Mar Piccolo basin represents a peculiar and sensitive environment and a social emergency because of sea water and sediment p...
متن کاملHydrogeological Issues Concerning the Thar Lignite Prospect
The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...
