The small, fully forested watershed Červík (CE) is situated in the part of the Beskydy Mts called the Zadní hory Mts Since November 1953, water balance has been measured in this place with the goal to find out experimentally the changes of the outflow sums during and after the intensive renewal of the forest with a partly changed wood species composition. The measured data were statistically evaluated by the method of double mass curve. In 1962, the decision was made to divide the watershed area into two separate parts A and B. The research started there in 1966 after a twelve-year long calibration period without timber cutting. The stands in the sub-watershed CE-A were cut down in three times shorter intervals than it is common and were immediately renewed. In the CE-B part, the stands were not tended in order to observe visible differences in the sums of outflow in comparison with those in the CE-A part. The measured data were analysed by double mass curve and revealed only very small differences while influence of the environment appeared to be more significant.Keywords:forest hydrology; experimental watershed; accelerated forest renewal; long-term hydrological measurement; changes of water balance
