Abstract: Long monitoring of air temperature and precipitation for three catchments with up to 100 years series has been used as the input for the modelling of rainfall-runoff process and for the re-assessments of the evapotranspiration demand (ET.sub.demand./sub.). The resulting oscillations and the random changes of vegetation cover have been pursued as the indication of fluctuations also in the evapotranspiration. The intention is to appraise this complicated time series as the long-term process. The modified implementation of the conceptual model SAC-SMA enables the quicker simulation and facilitates also the conditions for automatic calibration of parameters in the used model; separately for individual, i.e. partial time intervals, namely with the diverse expected evapotranspiration. That process is to be identified simultaneously with the optimal parameters of the mode; the resulting actual evapotranspiration (ET.sub.act./sub.) is then represented as the modelling outputs, as such values could be hardly gained as measured or computed values, e. g. from other meteo-observations.
