Abstracts
The results of implementation of the National Climate Program in the area of study of climate change impact on water quantity and water quality of Ukrainian rivers are summarized. With purpose of assess the present impact of regional climate change, the complex statistical analysis of long-term air temperature and precipitation data series, as well as river flow data series, for different hydrological periods have been used. The results of calculation for ensemble of six GAOC models have been used to project changing air temperature and precipitation in the XXI century. The assessment of possible changes in a hydrological regime and water resources under possible climate change has been carried out based on approaches, which were developed by the State Hydrological Institute (Russia). Essential peculiarities for northern and southern rivers as well as for mountain ones were revealed. The territory with increased water stress due to a climate change is expected to be more than twice larger than the territory with a decrease in water stress. The researches of a climate change impact on water quality have shown that the ecological status of the most of rivers can get worse. The obtained results allowed developing of recommendations concerning adaptation measures.
