This paper presents a three-layer soil water balance model and the results achieved when applying it to meteorological data for the 20th century. The evapotranspiration calculations were based on the Priestly-Taylor method, combined with the estimation of stomatal resistance, while water transport in the soil was calculated as a function of soil water hydraulic conductivity. The data used to run the model were taken from the CRU database for the whole of the last century, involving about 1430 territorial grid points from all over Hungary. As well as detailed climate data, the soil texture, the thickness of three soil layers and the land use were also taken into account. The results showed that among the surface soil characteristics, the thickness of the soil layers had the greatest effect on evapotranspiration, and also contributed to the depth of drainage. Soil texture was most important for calculating the soil water content and actual evapotranspiration, while the land use influenced actual evapotranspiration and the water surplus.
