Comparison of some Methods to Estimation Reference Evapotranspiration for Mosul Area(Arbic)

Abstract

This study has been established for Mosul area by using climatic data and information for estimation of evapotranspiration by using methods (Blany–Criddle), kharrufa, pan evaporation,Fao penman montieth) and comparison between them to reach to the best method this study showed that pan evaporation equation has a very good determination factor with Fao-penman montieth because this method depend on simple and obtained information in comparison with other methods so that this method is a more suitable use for Mosul area this study showed that there is a correlation performance relationship between these method the value of determination factor for Blany – Criddle is (0.9922) and for pan evaporation is (0.9788) and Kharrofa equation (0.9536) in comparison with Fao-penman Montieth
