Post-fire evolution of ravel transport regimes in the Diablo Range, CA
Autor: H. L. Jacobson, D. L. Roth, G. Walton, M. Zimmer, K. Johnson
Publikováno v: Earth Surface Dynamics, Vol 12, Pp 1415-1446 (2024)
Post-fire changes to the transport regime of dry ravel, which describes the gravity-driven transport of individual particles downslope, are poorly constrained but critical to understand as ravel may contribute to elevated sediment fluxes and associat

Rarefied particle motions on hillslopes – Part 1: Theory
Autor: D. J. Furbish, J. J. Roering, T. H. Doane, D. L. Roth, S. G. W. Williams, A. M. Abbott
Publikováno v: Earth Surface Dynamics, Vol 9, Pp 539-576 (2021)
We describe the probabilistic physics of rarefied particle motions and deposition on rough hillslope surfaces. The particle energy balance involves gravitational heating with conversion of potential to kinetic energy, frictional cooling associated wi

Rarefied particle motions on hillslopes – Part 2: Analysis
Autor: D. J. Furbish, S. G. W. Williams, D. L. Roth, T. H. Doane, J. J. Roering
Publikováno v: Earth Surface Dynamics, Vol 9, Pp 577-613 (2021)
We examine a theoretical formulation of the probabilistic physics of rarefied particle motions and deposition on rough hillslope surfaces using measurements of particle travel distances obtained from laboratory and field-based experiments, supplement

Particle motion on burned and vegetated hillslopes
Autor: Tyler H. Doane, D. L. Roth, Joshua J. Roering, A. Zettler-Mann, David Jon Furbish
Publikováno v: Proc Natl Acad Sci U S A
Climate change is causing increasingly widespread, frequent, and intense wildfires across the western United States. Many geomorphic effects of wildfire are relatively well studied, yet sediment transport models remain unable to account for the rapid

Demonstration and Analysis of Rarefied Particle Motions on Hillslopes
Autor: Josh Roering, Sarah G. W. Williams, Tyler H. Doane, D. L. Roth, David Jon Furbish
During the last century, descriptions of sediment transport on the surface of Earth have been mostly deterministic and strongly influenced by concepts from continuum mechanics. The assumption that ...

Bed load transport and boundary roughness changes as competing causes of hysteresis in the relationship between river discharge and seismic amplitude recorded near a steep mountain stream
Autor: Emily E. Brodsky, Noah J. Finnegan, Florent Gimbert, Jens M. Turowski, Dieter Rickenmann, D. L. Roth, Alexandre Badoux
Publikováno v: Journal of Geophysical Research: Earth Surface
Journal of Geophysical Research: Earth Surface, 2017, 122, pp.1182-1200. ⟨10.1002/2016JF004062⟩
Journal of Geophysical Research
International audience; Hysteresis in the relationship between bed load transport and river stage is a well-documented phenomenon with multiple known causes. Consequently, numerous studies have interpreted hysteresis in the relationship between seism

Fluvial network analysis on Titan: Evidence for subsurface structures and west-to-east wind flow, southwestern Xanadu
Autor: D. L. Roth, Cynthia B. Phillips, Karl L. Mitchell, Devon M. Burr, R. E. Jacobsen, D. Viola
Publikováno v: Geophysical Research Letters. 36
[1] Data of Titan’s surface from the Cassini-Huygens mission show inferred fluvial networks interpreted as products of liquid alkane flow. Using synthetic aperture radar (SAR) data, we delineated drainage networks, measured network parameters, and
