2025年1月15日 · This study highlights the complex interplay between debris flow dynamics, sediment transport, and vegetation colonization. The findings contribute to the scientific knowledge of debris flow processes and can be used to inform land management decisions and mitigate the hazards associated with debris flows in similar environments.

Along with a 30-year daily flow simulation, this study explores the control of flow sequence and constant flow on debris flow transport through the Provo River network at different time horizons (Figure 1).

Linear transport infrastructure systems are often subjected to landslide and debris flow events. Hazard maps, as well as, direct risk estimation play an important role to mitigate related effects.

Morpho2DH is the horizontal two dimensional debris/mud flow analysis solver which can reproduce the transport and deposition process of debris/mud flow due to the landslides. Structures (ex. sabo dam, weir, house and so on) and horizontal distribution of erosion depth can be considered in the analysis.

2023年12月5日 · One of the keys to effectively simulating runoff-generated debris flows is modelling the erosion-deposition process. The commonly used approach for formulating erosion and deposition, although constrained by physics, suffers from a singularity in the presence of vanishing velocity, which poses a major challenge for practical applications.

2017年4月10日 · Here, the flow (i.e., clear water) refers to the process from precipitation and infiltration to runoff that is associated with debris-flow initiation and transport. The flow is not only an important contributing factor for the debris-flow formation, but is also viewed as a significant component of debris flows [31]. 2. Experimental Design. 2.1.

L WD can be transported in channels by debris flows or stream flow. Debris flow transport of L WD dominates steep, low-order channels. Debris flows entrain L WD lying in their paths, and transport pieces to lower-gradient channels (Keller and Swanson, 1979; Nakamura and Swanson, 1993). This paper primarily addresses fluvial

2024年2月6日 · At a Glance. Barren, charred landscapes are vulnerable to dangerous debris flows. The risk ramps up as the rainy season kicks into high gear. The USGS assesses debris flow risk in burn scar areas.

Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock flow down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors.

Results show that sediment transport in stream flows and hyperconcentrated flows is primarily supported by viscous shear and turbulent stresses, whereas grain collisional stresses play a significant role in debris-flow dynamics.
