The Jiuzhaigou earthquake on 8 August 2017, led to a significant increase in the amount of loose, solid material, which has been rich source debris-flow activity. In this paper, comprehensive prevention and control system consisting stabilization, blocking, deposition structures is proposed based topographic features gullies Valley. Taking Xiajijie Lake gully as case study, history formation disasters were analysed. This study proposes main principles well implementation measures, lateral...
The Hotan River, the sole river traversing Taklimakan Desert in northwest China, sustains a critical desert riparian ecosystem dominated by Populus euphratica. This habitat is integral to biodiversity maintenance. However, global climate change and anthropogenic disturbances have profoundly impacted landscape, leading fragmentation reduced environmental heterogeneity. Consequently, there has been notable decline P. euphratica populations. study aimed assess physiological resilience of under...
Abstract Lateral erosion is a critical factor that influences the formation and amplification of debris flows. However, our understanding bank retreat process in flow channels limited, which limits evaluation magnitudes prediction their activity trends. Herein, we conduct physical experiments to investigate mechanisms using five types soil multiple surges. The categorized into two stages: toe cutting collapse. Toe mainly caused by hydraulic erosion, collapse includes gravity form toppling...
Experimental analyses and prototype observations of a debris flow drainage channel with energy dissipation structures were performed in this study. On the basis 160 groups experiments, simple empirical relationship was proposed to determine roughness coefficient an structure section channel. The experimental results suggest that comprehensive gradually increases area section. Meanwhile, approaches smooth as decreases less than 10% area. Moreover, velocity measured validated effectiveness...
On 8 August 2017, an Ms 7.0 earthquake struck Jiuzhaigou Valley, triggering abundant landslides and providing a huge source of material for potential debris flows. After the flows were triggered by heavy rainfall, causing traffic disruption serious property losses. This study aims to describe flow events in Zechawa Gully, calculate peak discharges flows, characterize disasters, propose mitigation countermeasures control these disasters analyse effectiveness that implemented May 2019. The...
Wood is an important component of flash floods and debris flows in forested mountainous areas. To better understand the characteristics large wood (LW) movement its destructive effects on check dams, bridges, buildings, we conducted field investigations theoretical calculations flood process Keze gully Jiuzhaigou National Park (China). Based calculation method, magnitude amplification ratio peak discharge caused by clogging breakage processes associated with LW transport reached 2.83 to 3.03...
Abstract Debris flows are one of the most serious natural disasters on Earth and cause great losses in human life property each year. Check dams have been widely utilized debris flow hazard mitigation, over time, some control projects exceeded their designed service lifetime. However, processes stored sediment erosion with multiple surges after check dam removal unknown. Here, associated different reductions height (i.e., removed height) were revealed by physical experiments. The results...
Rock masses in engineering applications are often simultaneously soaked a moist environment and exposed to dynamic loads with different rates. It is therefore essential understand the mechanical behavior failure mechanism of rocks by considering coupled effects water saturation rate dependence. In this study, numerous compression tests were conducted on marble granite under oven-dried water-saturated conditions using split Hopkinson pressure bar apparatus. Some indices such as compressive...
