Keywords: Ephemeral gully erosion Erodibility Internal erosion Landslides Pipeflow Soil pipes. Abstract. Many field observations have led to speculation on the role of piping in embankment failures, landslides, and gully erosion. However, there has not been a consensus on the subsurface flow and erosion processes involved, and inconsistent use of terms have exacerbated the problem. One such piping process that has been the focus in numerous field observations, but with very limited mechanistic… Expand
In Situ Soil Pipeflow Experiments on Contrasting Streambank Soils
Abstract. Soil piping has been attributed as a potential mechanism of instability of embankments and streambanks. Limited field work has been conducted on quantifying and modeling pipeflow andExpand
Subsurface erosion by soil piping: significance and research needs
Abstract Soil erosion is not only a geomorphological, but also a land degradation process that may cause environmental damage affecting people’s lives. This process is caused both by overland andExpand
Sediment detachment and transport processes associated with internal erosion of soil pipes
Subsurface flow can be an important process in gully erosion through its impact on decreasing soil cohesion and erosion resistance as soil water content or pressure increases and more directly by theExpand
Modeling Internal Erosion Processes in Soil Pipes: Capturing Geometry Dynamics
The flow of water in a soil pipe and the resulting erosion of the soil pipe wall is simulated using a numerical solution of the Reynolds-averaged Navier–Stokes equations coupled with the well-knownExpand
Seepage weathering impacts on erosivity of arid stream banks: A new conceptual model
Field observations have indicated the formation of horizontal, pipe shape cavities, along gully and dry stream channel banks in the semi-arid region of the northern Negev Desert, Israel. Piping is aExpand
Agricultural land degradation by piping erosion in Chaco Plain, Northwestern Argentina
Abstract Soil piping has been pointed out as an important water erosion agent in a wide range of climatic regions. It is responsible for high soil losses in loess derived soils. The goal of thisExpand
Landslide hydrology: from hydrology to pore pressure
Rainfall-triggered landslides are among the most widespread hazards in the world. The hydrology in and around a landslide area is key to pore pressure buildup in the soil skeleton which reduces shearExpand
Hydrogeomorphic processes affecting dryland gully erosion: Implications for modelling
Gullies contribute high sediment loads to receiving waters and significantly degrade landscapes. In drylands, low annual rainfall and resultant poor ground cover, coupled with high-intensity stormsExpand
ADVANCES IN SOIL EROSION RESEARCH: PROCESSES, MEASUREMENT, AND MODELING
Abstract. Soil erosion by the environmental agents of water and wind is a continuing global menace that threatens the agricultural base that sustains our civilization. For over 70 years, ASABEExpand
Seepage-Induced Streambank Erosion and Instability: In Situ Constant-Head Experiments
AbstractThe effects of seepage on streambank erosion and failure are less understood compared to fluvial processes, especially the linkage between surface water and groundwater mechanisms. Field dataExpand

The Role of Subsurface Flow in Hillslope and Stream Bank Erosion: A Review
Sediment is one of the most common causes of stream impairment. Great progress has been made in understanding the processes of soil erosion due to surface runoff and incorporating these in predictionExpand
Understanding soil‐pipe flow and its role in ephemeral gully erosion
The role of soil pipeflow in ephemeral gully erosion is not well understood. Experiments were conducted on continuous soil pipes to better understand the role of internal erosion of soil pipes andExpand
Numerical analysis of soil pipe effects on hillslope water dynamics
Soil pipes are considered to drain off water from a hillslope and play an important role in the subsurface runoff generation process, thus reducing the slope failure susceptibility. However, soilExpand
Ephemeral gully erosion by preferential flow through a discontinuous soil-pipe
Abstract Subsurface flow through soil-pipes can contribute to ephemeral gully erosion but these soil-pipes are cut-off when tillage fills in the gully. The objective was to determine the effect ofExpand
Mechanisms of ephemeral gully erosion caused by constant flow through a continuous soil‐pipe
Ephemeral gully erosion is considered to be driven by convergent surface flow while the role of subsurface flow is often overlooked. This study sought to characterize and quantify the soil erosionExpand
Numerical calculation of soil pipe flow and its effect on water dynamics in a slope
A chain of connected macropores, which develops nearly parallel to the impermeable subsurface layer, is commonly found in hillslopes and referred to as a soil pipe. Field observations have revealedExpand
Soil properties controlling seepage erosion contributions to streambank failure
The majority of sediment leaving catchments may be from streambank failure. Seepage erosion of unconsolidated sand above a restrictive layer is an important erosion process in incised streams thatExpand
Factors controlling the spatial distribution of soil piping erosion on loess-derived soils: A case study from central Belgium
Abstract Collapsible loess-derived soils are prone to soil piping erosion, where enlargement of macropores may lead to a subsurface pipe network and eventually to soil collapse and gully development.Expand
How do disconnected macropores in sloping soils facilitate preferential flow
Runoff from hillslopes is generated by processes such as infiltration-excess and saturation overland flow, subsurface stormflow and subsurface return flow. Preferential flow through macropores canExpand
