Abstract:: In order to provide the theoretical basis for the study of soil erosion and sediment yield in small watershed, the characteristics of sediment redistribution under the new erosion background were discussed.In this paper,special dam on the loess hilly area was taken as an example,the fractal dimension was applied to analyze the variation of grain size composition and fractal characteristics of sediment,and study the characteristics of sediment redistribution.The results show that:from top to bottom,the grain size of sediment profile in small watershed presents the periodic distribution law of fine-coarse,and the thickness of sediment layer varies greatly and decreases with the deposition time; the silt is the main coarse particle size,average percentage content of coarse particle is 51.73%;the fractal dimension distribution of each layer in the section of the dam is between 2.60 and 2.78;the coarseness of sediment varies from 0.04 to 0.37 with an average value of 0.16.The sediment thickness decreases and the amount of fine particulate matter in sediment increases in small watershed with the deposition time.
