The aims of this study are evaluation of water use management and water use efficiency of Yamchi pressurized irrigation and Ghoorichay low pressurized (hydroflume) canals, with total area 3885 ha and located in Ardabil plain. Annual relative irrigation supply, Annaual relative water supply, relative rainfall supply, water productivity and irrigation water productivity, as physical water use efficiency and parameters pure and impure benefit of water use efficiency and pure and impure benefit of irrigation water use efficiency as economic parameters were calculated. Results showed that, for four years of 2011-12, 2012-13, 2013-14 and 2014-15 mean of irrigation deficit of Yamchi and Ghoorichay canals were calculated 28 and 43 percentage, respectively. For three years of 2012-13, 2013-14 and 2014-15 mean of water productivity in Yamchi and Ghoorichay canals was calculated 1.52 and 2.15 kg/m3 and mean of irrigation water productivity was calculated 2.16 and 4.08kg/m3, respectively. Mean of water pure and impure benefit for Yamchi canal were estimated 987.67 and 884.67 toman/m3 and for Ghoorichay canal were estimated 4028 and 9100 toman/m3 , respectively. Mean of irrigation water pure and impure benefit for Yamchi canal were estimated 12669, 1515.33 toman/m3 and for Ghoorichay were estimated 23988.33 and 6523.33 toman/m3, respectively.
