Determining Primary Drivers of River Bead Functionality in Mountain Headwaters Streams
AGU 2024
earth and planetary surface processes | 12 december 2024
Katie Larkin, Ellen Wohl
Wide, low-gradient, storage-dominated stream corridors known as beads alternate with narrow, steep, transport-dominated strings along mountain streams...

When Rotten is Good: Diversity of Decay State and Piece Shape Complexity of Large Wood in Rocky Mountain Streams
AGU 2024
earth and planetary surface processes | 12 december 2024
Ellen Wohl, Shayla Triantafillou, Anna Marshall
Naturally functioning forested river corridors include downed, dead wood in varying decay states. Variation in decay state among large wood pieces inc...

Trajectories of River-Floodplain Adjustments and Functions Following Compounding Wildfire-Flood Disturbances
AGU 2024
earth and planetary surface processes | 11 december 2024
Aleah Hahn, Nicholas Christensen, Daniel C White, ...
Wide, low-gradient segments within river networks (i.e., beads) play a critical role in absorbing and morphologically adapting to disturbances, includ...

Exploring the influence of morphologic heterogeneity and discharge on downstream transport in streams with multiple logjams: Insight from numerical models
AGU 2024
hydrology | 11 december 2024
Xiaolang Zhang, Audrey H. Sawyer, Kamini Singha, E...
Logjams in streams form complex morphologic features such as pools, bars, logjams, and branching channels that increase stream water storage and force...

Delineating process domains for logjams in river networks of the Southern Rockies, USA
AGU 2024
earth and planetary surface processes | 09 december 2024
Shayla Triantafillou, Ellen Wohl
Centuries of deforestation and human modification of river corridors, including removal of large wood, have greatly altered the abundance and influenc...

Hyporheic Flows around Two In-Line Channel Spanning Logs
AGU 2024
earth and planetary surface processes | 09 december 2024
Shih-Hsun Huang, Audrey H. Sawyer, Ellen Wohl, Jud...
The in-channel large wood structures in forested rivers are known to enhance hyporheic flow, which are bidirectional flows across the sediment-water i...

Channel‐Spanning Logjams and Reach‐Scale Hydraulic Resistance in Mountain Streams
GEOPHYSICAL RESEARCH LETTERS
02 september 2024
Elizabeth Follett, Ellen Wohl
Logjams create an upstream backwater of deepened, slower water, locally reducing bed shear stress. We compared hydraulic impact of logjam series ac...
Interactions of Logjams, Channel Dynamics, and Geomorphic Heterogeneity Within a River Corridor
WATER RESOURCES RESEARCH
14 june 2024
Anna Marshall, Ellen Wohl, Emily Iskin, Lucas Zell...
Natural rivers are inherently dynamic. Spatial and temporal variations in water, sediment, and wood fluxes both cause and respond to an increase in...
