AB - In this study, we investigated the effects of the debris flow model parameters such as bed slope, soil density and internal friction angle on mean volumetric concentration. While the soil density showed little effect on mean concentration under the condition from 2.5 to 3.0, the bed slope greatly influenced on mean concentration. The mean concentration was increased steeply in high bed slope over 30° and dropped to -50 in bed slope of 37° and converged to zero. In lower bed slope of 5°, friction angle showed minor effects on mean concentration. However, in high bed slope, as friction angle got smaller, the mean concentration increased steeply. Especially, at the range of 20° to 30° of friction angle and bed slope, the mean concentration jumped discontinuity. For the stable simulation in field case, it was thought that a proper mean concentration value should be applied in particular range of bed slope and friction angle.
