Title

Determining the Appropriate Values of Irrigation System Design Parameters Tape and Strip System with Two Continuous Flow Regimes and Decrease Flow

Pages

  177-187

Abstract

 Today, due to high water consumption in the agricultural sector and the water crisis in the country, efforts have been made to improve irrigation methods. Given that agricultural irrigation is still superficial, it is necessary to find a solution to improve these methods at a much lower cost than pressurized irrigation. The purpose of this study is to use SIRMOD software to determine the optimal values of design parameters such as length, flow and cut-off time in two continuous flow regimes and flow reduction in strip and stream irrigation systems. Using the SIRMOD model, 25 and 50% of the actual values of field length, inlet flow and cut-off time were generated. The results showed that with a reduction of 25 to 50% in the length and flow rate to the farm, evaluation indicators such as Application efficiency, storage efficiency, distribution uniformity, increase significantly And runoff ratio and deep penetration ratio were significantly reduced. The results of the effect of changes in tape length on evaluation indicators show that the amount of storage efficiency in the range (-0. 5 to +0. 25) is almost a constant value equal to 100, but in the range (+0. 25 to +0. 5) The efficiency has changed even in some places to 80, and the Application efficiency in most furrows is a value between (90 to 40). The results showed that the flow reduction method, while being effective in increasing the evaluation indicators due to the interruption of water flow by the farmer after the end of the progress phase, especially in strip irrigation, did not have a significant effect on increasing the indicators.
