Abstract

EVAPOTRANSPIRATION is a key parameter in water balance equations of hydrologic cycle. This parameter is used as potential (or reference crop) EVAPOTRANSPIRATION. Different methods have been proposed to calculate reference crop EVAPOTRANSPIRATION, which are almost different with each other with respect to data needs. In 1998, FAO proposed PENMAN-MONTEITH method as a standard method to estimate reference crop EVAPOTRANSPIRATION. One of the important parameters in this method is NET RADIATION, which should be calculated precisely. Since measuring devices for solar radiation are not installed in all meteorological stations, the NET RADIATION is calculated from sunshine hours and extraterrestrial radiation. In the present research, the necessary coefficients (as and bs) were calculated for Isfahan region from long-term data. The results showed that as and bs were 0.267 and 0.488, respectively. The minimum and maximum difference between monthly EVAPOTRANSPIRATION obtained from the newly coefficients and the ones suggested by FAO (i.e., 0.25 and 0.5) was 0.6 and 0.1 percent. So, the recommended coefficients by FAO could be used in Isfahan region.
