Abstract In order to explore the effect of microplastics(MPs) on soil water infiltration, five groups of MPs addition treatments (0,1,2,4,6g/kg) were set to study the effects of different MPs contents on wet front transport and cumulative infiltration volume through indoor soil column simulation, and evaluate the applicability of the main infiltration models in MPs contaminated soil. The results showed that the migration rate of wet front decreased first and then increased with the increase of MPs content. When the content reached T2 (MPs content was 2g/kg), the migration rate of wet front was the lowest, which was 0.146cm/min. Compared to CK treatment, the migration rate of T2treatment was 10.1% lower (P<0.05). The cumulative infiltration volume also decreased first and then increased with the increase of MPs content. When the content reached T2, the cumulative infiltration volume was the least, which was 14.68cm. The reason may be that with the increase of MPs content, the influence of MPs on soil permeability increases, and the influence is the greatest when it reaches T2; When the content continues to increase, a new infiltration channel is formed by the MPs to accelerate the infiltration although the soil permeability decreases. The wet front propulsion model, Kostiakov model and Philip model have good fitting effects, and the determination coefficient R² are greater than 0.99, among which the wet front propulsion model has the best fitting effect. This study can provide a reference for the effect of MPs on soil water infiltration process and improve the simulation efficiency of the model.
