According to the rules and regulations of water allocation in agricultural sector of Iran, optimum and economic amount of water should be determined and illegal and overuse of water would lead to termination of usage license. According to this study, the method of determination of optimum water use in agricultural sector of Iran is not compatible with sustainable management of water resources. Despite some revision of law and regulation of water allocation for agricultural purpose have been made so far, wasteful use of water is being seen mainly due to non-volumetric delivery of water, lack of water user participation, lack of guarantees and little cooperation of related public organizations. Revising national water document due to the reduction in available water, volumetric delivery of water, shorten the time period for usage licenses and reviewing water tariffs are some suggestions for protection and sustainable use of water resources in agriculture sector of Iran. %U https://jplsq.ut.ac.ir/article_67636_9e470df35ffb037695e8dcde97b84c02.pdf
