Evaluation of the appearing changes in water regime at Ráztoka and Červík basins in the Beskydy Mts.
The influence of vast salvage clear cutting in some hilly regions induced by acid rains is sometimes considered as a significant contribution to the disastrous character of the recent floods. Then the considerations having also partly emotional character, appeared, namely after large floods in the Morava and Odra Rivers in the July 1997 and in the Labe River basins in August 2002. The simulations of rainfall-runoff process for several experimental catchments have been carried out using daily time series up to 50 years long. The outputs of hydrological models SAC-SMA and BROOK´90 provide naturally the differences between observed and simulated discharge, which could show the tendencies in the runoff. They have been analysed and findings indicate the increases of runoff after deforestation. The differences between observed and simulated flows can be helpful also for the assessment of changes in evapotranspiration demands as the significant long-termed phenomenon.
