Abstract

Reference evapotranspiration (ET₀) is a critical component of water resources management and planning. Different methods have been developed to estimate ET₀ with various required data. In this study, Hargreaves, Turc, Oudin, Copais, Abtew methods and three forms of Valiantzas’ formulas, developed in recent years, were used to estimate ET₀ for the Pilbara region of Western Australia. The estimated ET₀ values from these methods were compared with those from the FAO-56 Penman-Monteith (PM) method. The results showed that the Copais methods and two of Valiantzas’ equations, in their original forms, are suitable for estimating ET₀ for the study area. A modification of Honey-Bee Mating Optimization (MHBMO) algorithm was further implemented, and three Valiantzas’ equations for a region located in the southern hemisphere were calibrated.
