- The aim of work was comparison of two water balance models with different degree of complexity to predict soil moisture in small hilly loess catchment and to compare results of the modeling with field measurement done with TOR probes. In the first "bucket" model soil is treated as a tank for water with definite capacity, in the second more sophisticatcd model elaborated in the FEFLOW software, soil properties are described by retention curve and soil moisture pattern is obtained as a solution of Richards equation. In both models actual evapotranspiration is modeled by FAO56 method. The results obtained from both models were acceptable with similar determination coefficient of about 0,8. However, simulation of soil moisture with the FEFLOW model is more accurate although it requires more parameters and seeking for stable numerical solution. On the other hand it is also more suitable to use in hilly terrain where horizontal soil water fluxes must be taken into account.
