Regularities in the formation of groundwater level regime in Moscow Region

The need to study and take into account regularities in the formation of groundwater regime and runoff, especially in the context of current climate changes, is demonstrated. Typical plots of groundwater level regime, the dependence of the amplitudes of their variations and the major statistical parameters on the depth to groundwater, and histograms of the occurrence time of extreme positions of its level are shown. Long-term trends in precipitation and groundwater levels are established and their statistical significance is estimated. The presence of cyclicity in groundwater level regime is analyzed. © 2005 MAIK "Nauka/Interperiodica".
