STRUCTURE OF THE INFORMATION SYSTEM OF KAZAKHSTAN FRESH GROUNDWATER RESOURCES

Abstract

Insignificant in general value of surface water resources, cross-border nature of major rivers, their almost complete exposure to impacts of technogenesis processes have predetermined wide use of fresh groundwater supply in Kazakhstan. Study of the groundwater resources demand engaging of large volumes of hydrogeological materials and data from related areas of expertise. Their accumulation and analysis were carried out within the frameworks of the unified geoinformation system of resources and reserves of fresh groundwater of the Kazakhstan Republic and allows systematizing and analyzing of data about groundwater resources, quality and its using. The system’s structure was development with account to interconnection of groundwater with all components of natural and man-made environment. Key information blocks distinguished in the system are the following: general information about hydrogeological object and environment; data of groundwater monitoring; fresh groundwater resources and reserves; groundwater deposits; man-made facilities; groundwater pollution; groundwater protection; availability of fresh groundwater resources. All data are accommodated in graphic, semantic and documental database. Semantic data is presented in tabular form and represents attributive information for graphics objects comprising cartographical documents. The system was created in ArcGIS environment. Data entered into the system was used for generating thematic maps of fresh groundwater resources, as well as for calculating various characteristics of groundwater, areas with certain sets of parameters etc. Operation of the information system demonstrates by the example of territory of West Kazakhstan.
