Simulation calculation is an important means in hydraulics research, and the construction and selection of appropriate mathematical models are of great significance for improving simulation accuracy and result effectiveness. This paper explores the simulation effects of common models in the field of soil infiltration under turbid water irrigation by means of comparative analysis between indoor test results and simulation calculation results. The results show that the 4 selected common models in the study all have high simulation accuracy, among which the Green-Ampt model achieves the best simulation effect. The simulation accuracy of the models is the highest under clear water conditions, while the higher the sediment content in turbid water, the lower the simulation accuracy of the models. The methods and conclusions can provide theoretical support and reference for relevant research and engineering construction.
