Due to the water crisis, wastewater utilization is an effective way to meet the water needs of plants and also reduce environmental pollution. In order to know the effect of treated and magnetic wastewater on Manning roughness coefficient, a study was conducted in the form of randomized complete blocks with three irrigation treatments with "wastewater outlet", "magnetic effluent" and "normal water" in four replications. Statistical analysis on the relative changes of the roughness coefficient in the design did not show a significant difference. At the same time, a decreasing trend was observed during the irrigation season in the roughness coefficient, which was expected due to the smoothing of the flow path and the effect of organic matter of the effluent on the bed. The magnetic field was not affected by the magnetism. Manning roughness values with more irrigation with effluent and magnetic effluent, in most cases had a decreasing trend, but due to the use of water, an increasing trend was observed in them. However, the increase in normal water treatment could not be analyzed according to the information of this project. There was no statistically significant difference between the treatments of the project.
