Abstract:: Check dam and sediment deposition characteristics play the important role in studying the progress of eroded sediment migration and characteristics. In this paper, we analyzed the thickness and grain composition of sediment in different soil profiles in check dam in wind-water erosion cross region, we discussed the spatial distribution characteristics of sediment, and its response to soil erosion and sediment transport process. The results show that the sediment presents a non-uniform change from the tail to the front of the dam, but the layers of sedimentary cycle gradually becomes thin as a whole, the thickness of the sandy layer is generally greater than that of the clayey layer; the sediment in different location of dam is mainly composed of the fine sand, the average content of fine sand is 59.77%, followed by silt (23.41%), clay (11.21%), coarse sand (5.62%); deposition of sediment particles gradually become coarse from the tail to the front of the dam, and coarsening degree becomes greater, the coarsening degree of sand horizon is bigger than that of the clayey layer.
