Steep, soil-mantled hillslopes evolve through the downslope movement of soil, driven largely by slope-dependent transport processes. Most landscape evolution models represent hillslope transport by linear diffusion, in which rates of sediment transport are proportional to slope, such that equilibrium hillslopes should have constant curvature between divides and channels. On many soil-mantled hillslopes, however, curvature appears to vary systematically, such that slopes are typically convex… Expand
Hillslope evolution by nonlinear, slope‐dependent transport: Steady state morphology and equilibrium adjustment timescales
Soil-mantled hillslopes are typically convex near the crest and become increasingly planar downslope, consistent with nonlinear, slope-dependent sediment transport models. In contrast to the widelyExpand
Hillslope evolution by nonlinear creep and landsliding: An experimental study
Landscape evolution models are widely used to explore links between tectonics, climate, and hillslope morphology, yet mecha- nisms of hillslope erosion remain poorly understood. Here we use aExpand
Particle transport over rough hillslope surfaces by dry ravel: Experiments and simulations with implications for nonlocal sediment flux
[1] Past studies of hillslope evolution have typically assumed that soil creep processes are governed by a linear relationship between local hillslope angle and transport distance. The assumption ofExpand
Evaluation of linear and nonlinear sediment transport equations using hillslope morphology
Abstract Although some simple erosive processes like soil creep or tillage redistribution may be satisfactorily described by linear diffusive equations, the complexity of erosion phenomena requiresExpand
Gopher bioturbation: field evidence for non-linear hillslope diffusion.
It has generally been assumed that diffusive sediment transport on soil-mantled hillslopes is linearly dependent on hillslope gradient. Fieldwork was done near Santa Barbara, California, to develop aExpand
From divots to swales: Hillslope sediment transport across divers length scales
[1] In soil-mantled steeplands, soil motions associated with creep, ravel, rain splash, soil slips, tree throw, and rodent activity are patchy and intermittent and involve widely varying travelExpand
Slope, grain size, and roughness controls on dry sediment transport and storage on steep hillslopes
Existing hillslope sediment transport models developed for low-relief, soil-mantled landscapes are poorly suited to explain the coupling between steep rocky hillslopes and headwater channels. Here weExpand
Sediment transport by runoff on debris-mantled dryland hillslopes
[1] Hillslopes supply sediment to river channels, and therefore impact drainage basin functioning and evolution. The relationship between hillslope attributes and sediment flux forms the basis ofExpand
Responses of soil‐mantled hillslopes to transient channel incision rates
[1] Channel incision drives hillslope morphology in humid soil-mantled landscapes. When channel incision rates change, numerous hillslope soil properties (e.g., erosion rates, soil thickness, andExpand
How well can hillslope evolution models “explain” topography? Simulating soil transport and production with high-resolution topographic data
The morphology of hillslopes is a direct refl ection of tectonic forcing and climatic and biologic processes that drive soil production, mobilization, and transport. Soil transport on hillslopesExpand


Hillslope evolution by diffusive processes: The timescale for equilibrium adjustments
Diffusive processes such as creep, rain splash, and biogenic transport play a major role in controlling the development of convex hilltops on soil-mantled landscapes. Although many diffusion-basedExpand

Erosional escarpments are common features of high-elevation rifted continents. Fission track data suggest that these escarpments form by base level lowering and/or marginal uplift during rifting,Expand
Hillslope processes, drainage density, and landscape morphology
Catchment morphology and drainage density are strongly influenced by hillslope processes. The consequences of several different hillslope process laws are explored in a series of experiments with aExpand

Stochastic forcing of sediment supply to channel networks from landsliding and debris flow
Sediment influx to channel networks is stochastically driven by rainstorms and other perturbations, which are discrete in time and space and which occur on a landscape with its own spatialExpand
