Bedload and wash load have been measured using indirect method such as pipe hydrophone and turbidity meter, for the basin monitoring and sediment management in the basin, and those monitoring are conducted at around ninety sites in mountainous basin in Japan. There are few researches for comparative studies of differences of sediment runoff on basin characteristics. In present study, characteristics of sediment runoff and related controlling factors were discussed using monitoring data in representative six basins with different characteristic of water and sediment runoff. Several groups were classified with sediment runoff for flow discharge and sediment transport capacity. Monitoring for sediment and water runoff could be effective tools for basin monitoring through present data analyses.

Key wordsFsediment runoff, pipe hydrophone, turbidity, bedload, wash load
