Factor influencing headcut migration within a cohesive Texas Black-Land gully.
… studies have assessed the factors influencing headcut development in cohesive gullies, mainly due to the limitations posed by field instrumentation and the high shear strength of clay soils. Cohesive gullies, e.g. those found in Vertisols may be regarded as an end member gully types in erosion …

Headcut retreat resulting from plunge pool erosion in a 3D landscape evolution model
Headcut retreat produced by plunge pools is represented using existing concepts about this type of erosion. The model estimates retreat rates, given flow, height of the headcut, upstream slope and Manning's roughness, and the relevant soil parameters (erodibility and critical shear stress). The …

Levee Breach by Overtopping: The Effects of Soil Properties
… on breach discharge, breach width evolution and headcut migration are presented and shown to be linked to soil properties. A set of nondimensional equations to describing the breach process, i.e. peak discharge, time to peak, breach width evolution, final breach width and headcut migration, as …

Implications of Best Management Practices on Channel Evolution within the Bad River Watershed: West Central South Dakota
… absent. Dense PCG sites were associated with low headcut density, wide bankfull widths, high width:depth ratios, wide floodprone widths, and channel succession events trending toward decreasing stream power. Sites absent of PCG were associated with the opposite channel characteristics. Locations …
