Are there some significant proportional changes in water balance parameters of the forest watersheds in consequences of climate changes?

Yes, there are some significantly visible trends from let’s say 2013 showing changes in water balance parameters of forested watersheds in Central Europe. Generally, it could by claimed that the ratio between the evapotranspiration and discharge has started to change when there was marked decrease of discharge induced by the increase of evapotranspiration. For example, speaking about middle altitudes (so called uplands), we got the change of starting ratio 80:20 (evapotranspiration:discharge) to current 90:10.
