Analisis Evapotranspirasi dengan Menggunakan Metode Thornthwaite, Blaney Criddle, Hargreaves, dan Radiasi
Abstract
Abstract. The aim of this research is to analyze the evaporation using several methods, such as: Thornthwaite, Blaney Criddle, Hargreaves, and Radiation. Climatology data were taken from two climatological stations: Board of Meteorological, Climatology, and Geophysics of Blang Bintang and Climatology Station of Indrapuri in Aceh Besar District. The results showed that potential evapotranspiration (Eto) in Blang Bintang was higher than the potential evapotranspiration in Indrapuri. The differences of potential evapotranspiration occurred due to different methods used in the calculation. The highest potential evapotranspiration (Eto) obtained using Thornthwaite method and the lowest potential evapotranspiration (Eto) obtained using Radiation method. Temperature, precipitation, solar radiation, wind speed, moisture, air pressure, and the length of solar radiation were the factors that influenced the process of potential evapotranspiration (Eto). Several applicable methods in calculating the potential evapotranspiration (Eto) in Blang Bintang and Indrapuri were Blaney Criddle, Hargreaves and Radiation methods.
