Ascertaining of Evapotranspiration Series by Optimized Rainfall-Runoff Model

Popis výsledku v původním jazyce

Considerably long-term time series of precipitations and air temperature changes were used for modelling of the rainfall-runoff process. The time series were also utilised for the accurate assessment of the evapotranspiration demand for the Czech Elbe River. Random fluctuations of vegetation cover are to be taken as an indication of deviations in the evapotranspiration. The intention is to appraise such complicated time series as a long-term process. The recently modified software of the conceptual SAC-SMA model firstly enables a prompt simulation and secondly it creates the conditions for automatic calibration of this model. This tool provides a simulation separately for each partial time intervals with diverse expected values of evapotranspiration. This may be ascertained during the consecutive identification of optimal model parameters. The resulting evapotranspiration values are represented as outputs of modelling; these output values could hardly be gained from meteo-observations, e.g. measured data or computed values.
