Davybida L. Regional long-term forecast of natural regime of groundwater using GIS-technology (on example Zhytomyr and Dnipropetrovsk regions)

Dissertation is devoted to geological problems - time regional forecasting of natural regime of groundwater levels. The methodology of long-time regional forecasting natural regime of groundwater on a geoinformation approach basis has been developed. The quantitative analysis of accordance to the criteria of natural for groundwater regime has been given. The estimation of the regional long-term homogeneity of water-tables' regime is executed using GIS-technology. The analysis of observations of the groundwater's levels and characteristics of space, meteorological, hydrological and geodynamic factors shaping mode is executed. The basic rhythms of vibrations of subsurface waters' mode are definite in the investigated time series and the estimation of conformity to the law of many years changes of water-tables and their intercourses with the factors shaping mode have been given. Results are fixed in basis of time long-term prediction of change of water-tables.
