%X Infiltration can affect soil water recharge and soil water availability to plant, surface runoff and soil erosion. Although there have been many reports on infiltration for forest sites, none of them is conducted with muddy water. Muddy water is a type of available water resource with sediment from surface runoff and is used for irrigation in the semiarid and arid areas or direct into plantation sites. This study used 130 field sites i) to compare the infiltration of muddy water with tap water on black locust (Robinia pseudoacacia L.), oriental arborvitae (Platycladus orientalis Franco) plantation sites, ii) to understand the impact of sediment content, physical clay content of less than 0.01 mm in the sediment and tree species on infiltrability on forest soils with various texture classes on the Loess Plateau in China, and iii) to develop an universal model to describe water infiltration on the different forest soils in the region. The muddy water for the infiltration test was divided into four types according to sediment content, that is 50 g/kg, 100 g/kg, 150 g/kg and 200 g/kg; and each type of sediment content was further divided into three subtypes according to physical clay content, that is 220.0 g/kg, 249.0 g/kg and 263.0 g/kg for light loam in Ansai experimental station, and 419.0 g/kg, 446.0 g/kg and 481.0 g/kg for loam in Chunhua experimental station. Field infiltration was measured with a double ring infiltrometer at the water head (pressure) of 40 mm. A volumetric cylinder with an agitator was used to supply muddy water and recorded the amount of infiltration water manually. The results showed that muddy water decreased the infiltration capability of soil with light loam and loam, decreased the transfer capability of rainfall to soil water and impaired the role of forest in water conservation. The infiltrability decreased with increasing sediment content, physical clay content and infiltration duration; and was affected by soil texture. Under given soil texture condition, infiltrability of muddy water in plantation sites was affected by tree species. Infiltrability under black locust is superior to that under oriental arborvitae. The universal infiltration models for both muddy water and tap water were put forward for three stands of two different soil belts at the first time. The models can be used to evaluate the infiltration capacity of different muddy water in a plantation sites and predict runoff on a small watershed with different plantations.
