Field Survey of Sediment Deposit on Flood Plain on the Hinuma River

Field survey of sediment deposit on high water channel (flood plain) of the Hinuma river has been done to understand the deposit condition of sediment, which is suspended in low water channel at flood time, on high water channel. Through the study, the place where sediment deposit occurs is able to be estimated by using the ratio of frictional velocity to fall velocity of sand for both both high and low water channels.
