The objective of this study is to clarify the characteristics of the change in sediment height of each particle size with particle size distributions for deposition and erosion processes, and to develop the methods.Sediment mixture with different particle size distribution was used to measure the deposition height of each particle. The change in the deposition height of each particle was compared with the analysis result of the Eulerian packing model.
