Abstract: In the land phase of the hydrological cycle the evapotranspiration is one of the most important processes. The water resources planning, management for water supply and irrigation of agricultural areas required adequate information for the temporal and special variations of the evapotranspiration. The aim of the presented paper is to estimate and describe the evapotranspiration regime of Struma River - the biggest river in southwestern part of Bulgaria. In the presented paper a comparison between different methods for calculation of potential evapotranspiration (PET) such as Thornthwaite, Penman, Pristly&Taylor and Eagleman is realized. The mean monthly actual evapotranspiration is assessed according Turc’s empirical formulae. The long-term variability of evapotranspiration is analyzed.
