The Zonation of Aridity Intensity in Iran Using Hargreaves- Samani Evapotranspiration Model Based on Digital Elevation Model (DEM) by Taghi Tavoosi, Mohammadreza Mansouri Daneshvar, Alireza Movaqqari

“…Evapotranspiration rates have proved to be good indicators in estimating the severity of aridity in a region. because of the lesser errors of this method and the lack of recorded climatic parameters in many synoptic stations in Iran, In this study the Hargreaves – Samani method has been used to evaluate the evapotranspiration for 48 synoptic stations in Iran to calculate the evapotranspiration. Then, the spatial analysis was done based on DEM in GIS environment to produce the evapotranspiration maps. …”
