Abstract
Understanding and managing groundwater resources requires the integration of a large amount of high-quality data from various sources. Due to the limitations in access to information related to groundwater and subsurface conditions, the collection of available existing information is crucial when conducting a successful hydrogeological study. An approach to the development of a groundwater database is presented here. This spatial geodata database, implemented in GIS, is associated with a relational one. Since the basis of the information and analytical system for monitoring irrigated lands is a database, it allows the user to request relevant information. In addition, stratigraphic data stored in a spatial database can be used to build 3D models of underground structures. To store and analyze such a large amount of information, a system organization and automation of processing of many processes are required, so information support is an important part of monitoring.
