Abstract :
Iran is one of the countries that most of it has a warm climate, dry and semi-dry.The average rainfall in the world that is 860 mm and 240 mm in Iran Rainfall precipitation in Iran is very low . Meanwhile, with the increase and construction of wells excessive and uncontrolled exploitation of reserves of underground water in the water level drastically gone down and our country grew and population growth, it is necessary for the optimal use of water resources and Precipitation of modern methods of irrigation. That's why in this case study on the plain Arayez located in the city of Susa to investigate and compare the performance of your channel and one of the modern irrigation techniques the pipes of low pressure polyethylene hydraulically using the principles of design, drawings, documents Treaty, books, articles, pamphlets, calculations, hydraulic modeling, observations and field surveys of the materials, performance, time has run out. The results showed that due to fewer losses of water and efficient use of water, speed of operation and high ease of implementation, water delivery to beneficiaries in a shorter time, toss less land and more efficient use of hydraulic head water pipe of low pressure polyethylene on channel is preferred.
