The flood damage caused by a typhoon and the heavy rain was frequent in Japan. River management became important in such situation. The particle size distribution of the riverbed materials in the river channel was an important index from the viewpoint of sediment management. However, many considerations for particle size were related to the surface layer of the river bed.The examination about the riverbed materials at the deeper point was not carried out. These information was very important parameters to affect the precision of the numerical simulation.
