Mechanisms of wetting-induced loess slope failures
Landslides, 2019Frequent occurrence of landslides induced by rainfall or irrigation has seriously threatened the urban and rural development in the Loess Plateau, China. The increase in pore water pressure has been identified as a key factor for understanding wetting-induced loess slopes failures.

[Erosion process of loess slope and influencing factors in the loess hilly-gully region, China].
Ying yong sheng tai xue bao = The journal of applied ecology, 2021Rainfall intensity, slope length, and slope gradient are the important factors affecting runoff and sediment yield. In order to quantitatively analyze the effects of rainfall intensity, slope length, and slope gradient on the erosion process of Ansai loess slope in loess hilly and gully region, we analyzed the variation of runoff and sediment yield on ...

From the loess cliff to the gentle side slope: A predictable slope evolution
Quaternary International, 1993Abstract Slope stabilization in loess was studied by field observations and measurements with respect to the evolution of gully side-walls in the North American Midwest. Whereas parallel slope retreat appeared to characterize the unstable phase of the slope evolution (the ‘gully stage’), after a certain amount of stabilization, the reclining slope ...

Equation for Slope Sediment Transport Capacity With Respect to the Hydrodynamic on Loess Slope
Land Degradation & DevelopmentABSTRACT The sediment transport capacity of overland flow is a key parameter in soil erosion models, and accurately predicting this capacity is a critical challenge. Existing studies often overlook the effects of geomorphological changes and the interactions between runoff and sediment transport in actual soil ...

The impact of concentrated flow and slope on unpaved loess‐road erosion on the Chinese Loess Plateau
Land Degradation & Development, 2020AbstractLoess‐roads (LR) still experience severe soil erosion due to concentrated flow during rainstorms in watersheds on the Chinese Loess Plateau, where soil erosion in sloping farmland, abandoned land, and grassland has been controlled. However, road erosion is commonly overlooked because unpaved roads represent a small part of the catchment area ...

European Journal of Computational Mechanics
Based on the mutation theory, the paper studies the stability of loess slope, and discusses the loess slope in Yili region in Xinjiang. From the perspective of mechanics, the paper focuses on the influence of mutation phenomenon on the stability of loess slope, and deeply analyzes the mechanical mechanism in the mutation process.

DEM and image based loess slope segmentation
2010 3rd International Congress on Image and Signal Processing, 2010An integrated method combining digital terrain analysis (DTA) and object-oriented image analysis is used to classified loess slope into six types according to surface shape. Firstly, several data layers are extracted from Digital Elevation Models (DEM). Secondly, the data layers are combined into a multi-band image. Thirdly, object-based image analysis
