Different climates in Iran, including the northwestern regions (cold), southern coasts (hot and humid) central dry). TerraClimate network data (5 km resolution) from 40 years (1981–2020) was used to investigate changes trend breaking point of reference crop evapotranspiration (ETo) time series for different Iran. Statistical assessment indices (RMSE, R2, BIAS) were initially employed assess accuracy with ground stations. The temporal-spatial alterations trend, ETo, its extreme values then investigated using Mann-Kendall, Sen's Slope, Pettitt, Bayesian quantile regression tests. correlation coefficient between monthly gridded ETo calculated be more than 0.95, an average value BIAS –1.1. studied had increased. increasing tendency high highest slopes cold winter (slope >70 %), hot/dry spring summer hot/humid 50 %). Additionally, findings Pettitt's test suggest that three Iran a rising break autumn (hot/dry), (hot/humid) seasons, respectively. This indicates rapid have been common 1996 2000.

Energy demand, energy cost and water scarcity are three of the main problems in new Irrigation districts (ID) where irrigation distribution networks pressurized frequently organized on-demand (water is continuously available to farmers). This generates a huge degree uncertainty for IDs managers when it comes managing both use therefore its cost. Knowledge demand several days advance would facilitate management system help optimize costs. The artificial intelligence (AI) especially deep learning, developing forecasting model with capacity learn autonomously from real information each ID, key element achieve water-energy optimization. Previous works have successfully forecast at ahead. However, all these previous were based on human memory which fallible not easily pass operator next. In this work, combined modified version Transformer Neural Networks (TNNs), fuzzy logic Genetic Algorithms (GAs) middle-term time resolution (one-week ahead) ID scale has been developed tested working ID. improves representativeness accuracy best previously by 6.1 % 89.8 %, respectively. addition, only 9 attention heads 1.75 million parameters (only 16.7 denser than works) IWD was able 99.9 scenarios an average standard error prediction 2.10 %.

The accurate inversion of actual evapotranspiration (ETa) at a regional scale is crucial for understanding water circulation, climate change, and drought monitoring. In this study, we produced 1 km monthly ETa dataset Turpan Hami, two typical arid cities in northwest China, using multi-source remote sensing data, reanalysis information, the ETMonitor model from 1980 to 2021. We analyzed spatiotemporal variation various statistical approaches discussed impact land use cover changes (LUCC) on ETa. results show following: (1) estimation correlate well with products scales (coefficient determination (R2) > 0.85, root mean square error (RMSE) < 15 mm/month) high reliability. (2) values were spatially distributed similarly precipitation LUCC, multi-year (1980–2021) average 66.31 mm slightly fluctuating downward trend (−0.19 mm/a).
