The Chiyoda Experiment Channel, a section of the Chiyoda New Channel, is Japan s largest hydraulic experimental facility. It is capable of generating artificial flooding with a maximum discharge of 170 m3/sec. Experiments using this channel are planned to start in 2009. In 2007, we performed preliminary experiments to clarify the basic characteristics of the channel. The experiments used various types of observation instruments to measure the water level, discharge and sediment transport. The behavior of sediment in Chiyoda Experiment Channel was studied by examining bed load the channel bed height before and after water was introduced to the channel, and the bed materials, at varying discharges. The results were used to select the appropriate equation for calculating sediment transport in this experiment channel from among currently used equations of sediment transfer.
