Effect of debris-flow sediment grain-size distribution on fan morphology

Autor: H. Tsunetaka, N. Hotta, Y. Sakai, T. Wasklewicz

Publikováno v: Earth Surface Dynamics, Vol 10, Pp 775-796 (2022)

Knowledge of how debris flows result in the fan-shaped morphology around a channel outlet is crucial for mitigation of debris-flow-related disasters and investigation of previous sediment transport from the upper channel. Therefore, using a flume con

Relationship between the accumulation of sediment storage and debris-flow characteristics in a debris-flow initiation zone, Ohya landslide body, Japan

Autor: F. Imaizumi, Y. S. Hayakawa, N. Hotta, H. Tsunetaka, O. Ohsaka, S. Tsuchiya

Publikováno v: Natural Hazards and Earth System Sciences, Vol 17, Pp 1923-1938 (2017)

Debris flows usually occur in steep mountain channels and can be extremely hazardous as a result of their destructive power, long travel distance, and high velocity. However, their characteristics in the initiation zones, which could possibly be a

Basal interstitial water pressure in laboratory debris flows over a rigid bed in an open channel

Autor: N. Hotta

Publikováno v: Natural Hazards and Earth System Sciences, Vol 12, Iss 8, Pp 2499-2505 (2012)

Measuring the interstitial water pressure of debris flows under various conditions gives essential information on the flow stress structure. This study measured the basal interstitial water pressure during debris flow routing experiments in a laborat
