Abstract

Recently hydrological mapping have gained renewed interest in connection with climate-change impact studies, determination of water budgets at different temporal and spatial scales and the validation of atmospheric simulation models and hydrological models. Grids maps are often chosen for the representation of the spatial distribution of diverse physiographic and hydrologic information. This study focuses on the spatial estimation of the long-term mean annual actual (ET) and potential (EP) evapotranspiration in mountainous basins in Central Slovakia. Three methods used for EP and ET estimations are compared in a mapping framework: the modified empirical Turc model, the energy based SOLEI model and continuous water balance simulation using WASIM model. The spatial variability and consistency of EP and ET estimated by the different methods is evaluated and the performance of resulting ET grid maps is compared with the observed long-term water balance in three Hron river basins: river Hron to Bystra, Hron to Brezno and Hron to Banska Bystrica profiles.
