Calculation of potential evapotranspiration based on solar radiation income modeling in mountainous areas

This study proposes a methodology for both, solar energy income modelling and evapotranspiration modelling in mountainous areas. For that reason the SOLEI model which can calculate potential, as well as actual energy income to the slopes with different orientation and taking into account the shadowing of the surrounding topography was developed. The contribution presents results of calculation of potential evapotranspiration based on actual solar energy income modelling obtained in the Jalovecky creek experimental hydrological basin in the Western Tatra Mts.
