Considering that the surface irrigation system is one of the most widely used irrigation methods in the country, increasing the efficiency of this irrigation system is considered one of the country's main policies. In this research, by simulating surface irrigation flow using the method of solving Saint-Venant's equations (zero inertia method) in SIRMOD and WinSRFR software and comparing it with field observations in Ahvaz Sugarcane Research Center, the efficiency of the two softwares was investigated in the simulation of surface irrigation flow. Based on the analyzed statistical indicators, it was observed that in general, both softwares have a good ability to simulate the flow in furrow irrigation. Both models calculated the advance time and runoff more and the infiltration value less) than the measured values. In the investigation of furrow irrigation performance indicators, it was also found that the WinSRFR model simulation with higher application efficiency and lower runoff is closer to the measured data. Based on the results, the performance of WinSRFR software is better than SIRMOD software with a little difference (advance time 4%, infiltration volume 3% and runoff 6%). Also, it was observed that based on field experiments, the relative errors of inflow and infiltration water volumes were calculated by WinSRFR software 1.3, 2.7 and SIRMOD, 4.9% and 4.5%, respectively. In the estimation of runoff, the best and weakest performance was observed in the amount of 30.2 and 32.5 cubic meters, respectively, in WinSRFR and SIRMOD software
