Abstract

The aim of this study is to evaluate the estimated evapotranspiration with three methods of estimating
evapotranspiration (Priestley and Taylor (PT), Turc (T) and Hargreaves (HG)) in relation to the reference
method FAO 56 Penman Monteith (FAO 56 PM.) The evaluation is done from statistical analysis to stations
located in humid areas, semi-arid and arid Argentina. The results show the method of HG provides reliable
values of ET for areas of arid to semiarid climate and that is the fact that this methodology is easily
applicable and requires as input the equation values maximum and minimum temperature. Regarding the
humid zone, the equation of PT and secondly that of T, presented a better performance, both are practical
methodologies and less complex.
