Investigating interbasin virtual water in Sefidroud basin

Virtual water trade is investigated in industrial, agricultural, social sectors for national and global scales. In this study, interbrain virtual water was evaluated in irrigation sector for the Sefidroud basin to use in the allocation of water resources. In this regard, through investigating eight cropping pattern (S1- S8) in the riverbank of Qezelozan River (provinces of East Azarbaijan, Zanjan) during the years 2001-2025 were evaluated SWAT model. Data of Meteorological, hydrological river and crop yield for the years 2014- 2025, were produced using Minitab 17.0 software through ARIMA time series model. The results showed that cultivating dry- irrigated wheat (S6) is more appropriate in the East Azarbayjan and Zanjan province because of average of virtual water of wheat and rice is 2.73- 3.24 and 3.28- 4.06 (m3/kg) ,respectively. Also, excess water exchange for S6 from East Azarbayjan and Zanjan provinces to Gilan province resulted in to reduce virtual water of rice Guilan province.
