ESTIMATION OF REGIONAL CLIMATE CHANGE AND ITS INFLUENCE ON GROUNDWATER LEVEL (ON THE EXAMPLE OF ROSTOV ON DON)

Назаренко О.В.
It is given results of estimation climate influence on formation of groundwater. Correlation between climate and groundwater level was estimated. In natural, weekly disturbed conditions, the impact of the meteorological factors in the formation of groundwater level is 60 – 80%. The leading role is belonging to the humidity and evaporation. Rostov-on-Don is a big industrial centre and here leading role belongs to anthropogenic impact. In this case, there is a reduce of meteorological impact from 80% up to 20%. Groundwater level in Rostov-on-Don is increasing constantly due to technogenic effect, such as infiltration of leakage water. With increasing anthropogenic pressures on the territory of the role of meteorological component in the formation of the groundwater level is reduced. With the increasing of anthropogenic pressure role of the meteorological factors in groundwater formation decrease. The use of spring water for drinking purposes on the territory of the city is not possible due to the lack of monitoring and the high level of contamination.
