Outline of Final Research Achievements

Detailed field measurements of debris flow in the Ohya landslide revealed two issues to be solved for model development to predict sediment dynamics after huge landslide occurrence. One is influence of particle size distribution of debris-flow material on the fluidity. The other is meandering of debris flow on a debris fan at the bottom of catchment. The influence of particle size distribution was appeared as liquefaction of fine particles. Also, some of solid particles merely contribute to static stress without any contribution to dynamic stress. The particle size affected the meandering on a debris-flow fan as well. Experiments with uniform particle size showed straight descending on a debris-flow fan, while debris flows with mixed particle size showed meandering on the fan leading asymmetrical and variable final shape. Accumulation of coarse grains at the debris-flow front induced rapid and unsaturated deposition at the fan apex and possibly caused the following meander movement.
