Abstract

The most important of design and exploitation of water supply systems for agricultural needs, is the Estimation of crop water requirement. This aim of is studing the impact of climate change on evapotranspiration phenomena at five stations in the dry, semi-dry, Mediterranean, humid and very humid climates, using HadCM3 general circulation model under two scenarios A2, B1 for Near future (2039-2010), the intermediate future (2069-2040) and the Far future (2099-2070) and the period 2000-1971 as the base period and downscaling process is asssessed by Proportional downscaling and change factor methods. The potential evapotranspiration for five stations was calculated using Monteith, Makkin, torque wet and dry areas, Priestley- Taylor , Hargreaves - Samani and Blany‌Keridel methods was calculated The results showed that in the ET will increase by 12% and decrease by 35% in winter and summer, respectively. Stations the climates with more humidity greater impact of climate change is accepted. The changes in evapotranspiration stations A2 scenario will occur in the distant future. For future periods, the Priestley-Taylor method has more proximity with FAO- Penman-Monteith Than the other methods model and stations having high humidity climates will be affected more by climate change
