Flow hydraulics consideration information of the grey water reuse: towards sustainable water management

In this article, the effect of water quality on the hydraulic parameters of furrow irrigation was tested with 60 experiments with the quality of fresh water (FW), magnetic (MW) and non-magnetic effluent (WW). It was found that magnetism has no significant effect on the quality parameters of wastewater. Also, the effect of water quality on infiltration parameters such as final infiltration, average infiltration in certain time periods, especially in the advance stage, was not significant. But the final penetration reduction during the test period in MW and WW was more severe than FW and magnetism had little effect. These observations were similar to the results in the average penetration in certain time intervals except for the advance stage. Water quality did not have a significant effect on the time of discharge and progress and regression and the time of reaching the final infiltration. The results showed that the hydraulics of furrow irrigation was more affected by the soil and tillage than the quality of irrigation water and the magnetic field did not change the hydraulic effects of WW compared to MW.
