1-2. füzet - Szalai József: A hidrológiai közelmúlt sajátosságai a talajvíz szintekben

168 Szalai József A higher than ever groundwater level subsidence was observed in 2000 in the SE part of the region between the rivers Danube and Tisza. In the years of the near past there seems to be a new equilibrium state of the groundwater table reached at lower levels than before, suiting the changed external conditions. The examples shown reflect no exceptional events but reveal the fact that processes resulting in the trend-like groundwater subsidences of the past years had occurred also in earlier decades. When the conditions will be more favourable ones for the budget of the groundwater resources one may expect the rise of the groundwater tables as well. Nevertheless one must consider such changes of the groundwater table as a warning sign of the sensitivity of groundwater resources to the joint effect of natural hydrometeorological conditions and anthropogenic impacts of a given region.
