GEOINFORMATIONAL DATABASES OF THE DATA OF HYDROGEOLOGICAL PARAMETERS OF ARTISIAN WELLS OF THE TERRY-KUM ARTISIAN BASIN

Abstract

Modern geoinformation (GIS) technologies make it possible to store and process a variety of spatially-distributed data accumulated by mankind as a result of economic activity. Using such technologies can display the spatial information in form of various electronic cards. This kind of organization of data allows on a high scientific and methodological level to solve a wide range of scientific and applied problems related to natural resource management and environmental protection. This article describes how to develop geographic information database (DB) of the Terek-Kuma artesian basin (TKAB), provides the structure of the base, and suggests examples of its using when solving various geotechnical problems. It is shown how, based on the information from the database, to develop special thematic maps which have a sufficient degree of accuracy, required when solving problems of analysis and forecast of development of various geological processes, arising from the use of natural resources in the economic activity. Using all available data on a hydrogeological object, including those stored in the databases of graphic and semantic data, the article describes the method of creating mathematical models of artesian basins (on the TKAB example). Different requirements for system models are suggested, objectives and modeling tasks are detailed, and various criteria for quality assessment of solutions, decision deadlines, financial, human, material resources, etc. are defined.
