Abstract Landslide‐induced debris flows can travel long distances. Many field studies, laboratory experiments, and theoretical studies have been conducted to clarify the mechanisms of long‐runout landslides. However, information concerning landslide‐induced is still inadequate despite several explanations proposed. Thus, we collected various forms data, including video images light detection ranging for a flow that occurred on 28 July 2015, in Fukaminato River, Japan, clarified behavior from...
Physically based numerical simulation models have been developed to predict hazard area relating debris flows. Since fine sediments are expected behave as a part of the fluid rather than solid phase in stony flows, several recently included this process shift from context sediment. However, not fully tested regarding ability reproduce variety flow characteristics. We therefore (i) applicability model for describing characteristics and (ii) effect sediment on behaviors. Herein we applied...
It is widely recognized that the effects of a phase shift fine sediment in large-scale debris flows are likely to be large. Therefore, numerical simulations, it essential describe sediments fluid phase, and not solid phase. Recently, "Kanako" simulator has been used for variety objectives, particularly because graphical user interface. However, date, there no available simulation model includes shifts. Here, we present modified version Kanako this sediment. In new simulator, which refer as...
Deep catastrophic landslides (DCLs) sometimes lead to large-scale debris flows with serious impacts on human life and infrastructure. However, no adequate information about DCL-triggered flows, such as the topography of eroded deposited areas or grain size distribution, exist. We compiled published data obtained additional new for topographic characteristics distributions 10 recent in Japan. compared these previously small-scale steep-slope failures, flows. examined effects DCL volume...
Stony debris flow transits to sediment sheet when the river bed gradient becomes gentle. The consists of a water layer and moving layer. Fine sediments are expected behave as part fluid rather than solid phase in Further, it can be thought that fine suspended However, was not possible physically express whether behaves or numerical simulation model. Here we modeled behavior flow. We confirmed applicability new model describe longitudinal deposited flume experiments.
