Groundwater filtration is a very complicated process determined by natural environmental factors and anthropogenic impacts. Credible predictions of impact of extortions on the groundwater environment require application of appropriate research methods which will enable detailed representation of the groundwater circulation. Such methods include numerical modeling of filtration processes and application of mathematical description of groundwater flow, based on assumed hydrogeological parameters and boundary conditi...

A concept of Geographical Information System (GIS) refers to a special system developed to collect, store, analyse and visualise geographical spatial data and related attribute data. GIS is not only a software which enables the system, but it also comprises collected data and specific organisational procedures. The most important advantages of GIS include the possibility of connecting spatial data and described attributes derived from different sources, and above all пїЅ the ability to perform geospatial analyses....

The construction of a numerical hydrogeological flow model must be preceded by obtaining necessary information. Quantity and reliability of information may extensively impact on the process of model construction and its later calibration, and as a result пїЅ the quality and reliability of prognostic calculations. The article deals with sources of data required for a numerical groundwater flow model and it presents various types of data resources. The model is based on a number of overall nature materials, such as ...
