Groundwater is the most dynamic and vulnerable component of the geological environment, which in real-time responds to changes in natural and natural-anthropogenic factors and defines the emergence and intensification of the dangerous geological processes, particularly such as landslides, ground subsidence, flooding, etc. To assess the impact of various factors on the exogenous geological processes (EGPs) development and intensification, primarily the most fast-changing ones, in addition to meteorological conditions (precipitation amount and its seasonal distribution) hydrogeological conditions, and the most volatile indicator - groundwater level – are taken into account. Continuous territory monitoring requires numerous complex and diverse problem solutions, including reasonable and comprehensive forecasting of changes under the influence of physical, chemical, and biological factors based on modern information technologies. Given that National Kyiv-Pechersk Preserve territory has a complex relief with a height difference of 74.5 m from south to northeast in real terms, it is necessary to conduct constant monitoring and landslide prevention activities, carry out surface water drainage measures, replace water supply and disposal communications, and determine the impact of changes in groundwater regime on the territory to achieve the ultimate objective. This multifaceted process can be optimized by a geodatabase, the use, and maintenance of which will enable to focus on the study of the hydrogeological conditions, in particular the groundwater regime and the nature of aquifers changes.
