Mechanistic models have been proposed for soil piping and internal erosion on well‐compacted levees and dams, but limited research has evaluated these models in less compacted (more erodible) soils typical of hillslopes and streambanks. This study utilized a soil box (50 cm long, 50 cm wide and 20 cm tall) to conduct constant‐head, soil pipe and internal erosion experiments for two soils (clay loam from Dry Creek and sandy loam from Cow Creek streambanks) packed at uniform bulk densities… 
Bench-Scale Experiments on Effects of Pipe Flow and Entrapped Air in Soil Layer on Hillslope Landslides
Soil pipes are commonly found in landslide scarps, and it has been suggested that build-up of pore water pressure due to clogged soil pipes influences landslide initiation. Several researchers have
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 the

The role of soil pipe and pipeflow in headcut migration processes in loessic soils
Headcut formation and migration was sometimes mistaken as the result of overland flow, without realizing that the headcut was formed and being influenced by flow through soil pipes into the headcut.
Hydromechanical constraints on piping failure of landslide dams: an experimental investigation
BackgroundUnderstanding the internal structure and material properties of landslide dams is essential for evaluating their potential failure mechanisms, especially by seepage and piping. Recent
On the effect of compaction on the progression of concentrated leaks in cohesive soils
The purpose of this study is to conduct hole erosion tests (HETs) to better understand the progression of concentrated leaks in compacted soils. While samples with high levels of compaction have been
Multi-objective optimization of erosion parameters of erodible soils using Taguchi-based gray relation analysis
Internal erosion caused by piping poses threats to the efficiency and stability of earthen structures like dams, dikes, levees, and water barriers. The severity of erosion incidents causes soil
Stability Improvement Method for Embankment Dam with Respect to Conduit Cracks
In recent years, as the number of reservoir embankments constructed has increased, embankment failures due to cracks in aging conduits have also increased. In this study, a crack in a conduit was
Relationship between seepage water volume and total suspended solids of landslide dam failure caused by seepage: an experimental investigation
Background Landslide dams inevitably demonstrate the potential for catastrophic failure with high-risk damage to life and property at the downstream site. Hence, knowledge of the internal stability
Laboratory investigation of erosion behavior at the soil–structure interface affected by various structural factors
Being regarded as an elementary contact unit in the foundation and embankment of levees, trenches and other engineering constructions, the soil–structure interface is highly susceptible to erosion by


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 and
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 and
Erosion of Noncohesive Sediment by Ground Water Seepage : Lysimeter Experiments and Stability Modeling
Seepage may be a significant mechanism of streambank erosion and failure in numerous geographical locations. Previous research investigated erosion by lateral subsurface flow and developed a sediment
Sediment Transport Model for Seepage Erosion of Streambank Sediment
Erosion by lateral, subsurface flow is known to erode streambank sediment in numerous geographical locations; however, the role of seepage erosion on mass failure of streambanks is not well
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 that

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 erosion
