Abstract :

Iran is one of the countries that is weathered in most of its regions with hot, dry and semi-arid weather. According to the average rainfall in the world, which is 860 mm in Iran and 240 mm in Iran, rainfall in Iran is very low.Meanwhile, with the increase and construction of wells and the abundance of underground water reserves, the surface of these waters has fallen sharply, with increasing population, it is necessary to use modern methods of irrigation for optimal use of aquifers and cemeteries.For this reason, in this study, a case study was carried out in Araez Plain, located in the city of Susa, and compared the implementation of canal and one of the newest methods of irrigation, polyethylene low pressure pipe, using hydraulic, using the basics of design, maps, documents Contract, books, articles, pamphlets, calculations, hydraulic modeling, observations and field visits from the stages of material supply, implementation, duration of implementation.The results showed that due to lower water losses and optimal water use, the speed of operation and ease of implementation, the delivery of water to operators in shorter time, less land plots, and the optimal use of hydraulic hydraulics, polyethylene low pressure pipe Canal is preferable.
