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 internal erosion processes in the field with either natural or artificially created soil pipes. This research utilized an innovative constant-head trench system to conduct constant-head soil pipe experiments in two contrasting streambanks: Dry Creek in northern Mississippi and Cow Creek in northern…

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.
Effects of pipe outlet blocking on hydrological functioning in a degraded blanket peatland
Peatland restoration practitioners are keen to understand the role of drainage via natural soil pipes, especially where erosion has released large quantities of fluvial carbon in stream waters.
Laboratory soil piping and internal erosion experiments: evaluation of a soil piping model for low‐compacted soils
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
Effect of air mobility in a soil pipe on water flow through a model hillslope after pipe clogging
Soil pipes (continuous macropores expanding laterally in the soil subsurface) are a key factor controlling hillslope water cycles and sediment transport. Soil pipes usually enhance slope stability

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 revealed

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 prediction
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
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

Since the 1980s, several field studies of pipeflow hydrology have been conducted in forested, steep headwater catchments. However, adequate information is lacking with regard to questions as to how
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
