  • Abstract en The engineering objective of this research is to understand the processes of sediment transport and its spatial and grain-size distribution for preventing flood disaster as well as conserving river environment. To address this concern, we are conducting field survey on Saru river basin since 1997 to measure discharge and various water quality items. In August 2003, Hidaka subprefecture was ravaged by torrential rains and this event triggered over 4, 000 slope failure occurred in Nukabira river basin, a tributary of the Saru River (a Class-A river). The disaster of this flood, huge amount of driftwood and muddy flow inundated resident area and farmland, made strong social concern. This paper summarizes brief overview of this flood and investigation result using remote sensing data and field survey. Finally we found the followings:(1) 30% of the slope failure reaches stream and injected sediment. Sediments from slope failure was deposited on upper reaches and carried downstream by the flow as washload.(2) 90% of the newly deposited sediment at dam reservoir was washload which under 0.2mm grain size.
