Research Abstract	Sedimentary structures and their depositional processes of coarse-grained foresets were investigated by description of Tertiary fandelta deposit and flume experiments using mixed-sized sediments. During a foreset deposition, the different behaviors of sediment grains due to their diameters are important on the transition of a foreset sedimentary structure, i.e., diffusion of fine grains and depletion of coarser grains, mixing of grain-flow of granules and fines, and sorting processes within grain flows.
