Abstract

In the paper a methodology for estimating monthly potential evapotranspiration (E0) as an input for hydrological balance modelling in the upper Hron River basin was developed. Four different methods were used to calculate monthly potential evapotranspiration in 6 climate stations in the basin – the Tomlain method based on equations of energy balance, the FAO method based on equations of radiation balance and empirical parameters, and 2 empirical methods – the Thornthwaite and Ivanov methods. Because of the relatively different results of E0 values estimated by these 4 methods, the physically based Tomlain method was considered as a reference method. Other methods containing empirical parameters were calibrated to estimate E0 with the best agreement to the Tomlain method. Calibration was done for each method and individual climate station, as well as for the whole region and was aimed to find a regional set of parameters for methods of E0 calculation. The method of genetic algorithm was used for the calibration. The efficiency of E0 computed by each of the calibrated methods was compared with the Tomlain method and the results were used for modelling of the hydrological balance in the basin.
