Stable isotope techniques can be used to investigate evapotranspiration and its partitioning into evaporation transpiration. However, verification is often difficult due missing information about actual evapotranspiration. Therefore, in this study a methodology tested for laboratory conditions was modified field applications. Evapotranspiration, which determined by weighing lysimeters, were com...

Evaporation is a fundamental parameter in the hydrological cycle. This study examines the performance of M5model tree and artificial neural network (ANN) models in estimating potential evapotranspiration calculated byPenman- Monteith and Hargreaves- Samani equations. Daily weather data from two meteorological stations in asemi-arid climate of Iran, namely Kerman and Zahedan, were collected duri...

Wheat is an important crop of India. Precise estimates of evapotranspiration can be obtained by multiplying crop coefficients to reference evapotranspiration using readily available climatic data. PenmanMonteith equation is adopted world wide as the most reliable and accurate method for computing reference evapotranspiration. The Food and Agriculture Organization (FAO) presented crop coefficien...

Global warming has accelerated surface water loss around the world. This study investigates in detail change and attribution of potential evapotranspiration (PET) across China from 1901 to 2100 by Hargreaves model, based on a 1-km temperature dataset downscaled low-spatial-resolution datasets using Delta downscaling framework. Results showed that (1) relative 1961–1990, PET increased 0.62% hist...
