Sediment transport and deglacial incision of the upper Mississippi River inferred from luminescence dating Open
As rivers sculpt their valleys and floodplains, they transport sediments – primarily quartz and feldspar – from source regions to the sea. These complex sediment-transport processes, difficult to study even over short time scal…

A Sedimentologic, Morphometric, and Geochronologic Investigation of Ambiguous Dune-like Landforms: An Indicator of Proglacial Lake Drainage in the Lake Superior Basin, USA Open
Preliminary observations of three trains of dune-like landforms, just south of the shore of Lake Superior, near Christmas, MI, USA, reveal the presence of large and imbricated boulder clasts on their surface and 20–33 m deep bedrock …

Rules of River Avulsion Change Downstream Open
Avulsing rivers carve new pathways on the floodplain, and the associated flooding can profoundly impact society 1-4. River avulsions are thought to occur when the water column becomes perched above the floodplain5, or when the slope down t…

Sedimentary Processes and the Temporal Resolution of Sedimentary Strata Open
An appealing strategy for reconstructing the timing and tempo of paleoenvironmental change from sedimentary strata is to linearly interpolate between marker beds of known age. This method requires significant assumptions, but more advanced…

Reconstructing backwater hydrodynamics from fluvial-deltaic deposits using stratigraphic inversion: An example from the Tullig Sandstone, Western Irish Namurian Basin, County Clare, Ireland Open
Fluvial-deltaic systems are subject to non-uniform backwater flow where rivers approach receiving basins. This hydrodynamic condition results in sediment aggradation on the channel bed and enhanced downstream fining. In turn, this impacts …

Review Open
Abstract. The early Cenozoic marine sedimentary record is punctuated by several brief episodes (< 200 kyr) of abrupt global warming, called hyperthermals, that have disturbed ocean life and water physicochemistry. Moreover, recent studies …

Similarity of stream width distributions across headwater systems Open
The morphology and abundance of streams control the rates of hydraulic and biogeochemical exchange between streams, groundwater, and the atmosphere. In large river systems, the relationship between river width and abundance is fractal, suc…

Comment on esurf-2021-82 Open
Abstract. River avulsions are an important mechanism by which sediment is routed and emplaced in foreland basins. However, because avulsions occur infrequently, we lack observational data that might inform where, when, and why avulsions oc…

Transitions in flooding intensity on an experimental delta Open
Information about past environments is stored in sedimentary rocks via biogeochemical markers stored in the sediments. Using these markers, the signal of paleoclimate and other environmental factors can be reconstructed from the strata. Ho…

Abstract. Traditionally, interactions between tributary alluvial fans and the main river have been studied in the field and in the laboratory, giving rise to different conceptual models that explain their role in the sediment cascade. On t…

Headwater streams, despite being a significant natural resource, and a critical element of the hydrosphere, remain an understudied system. Anyone who has observed small creeks and rivers closely will know that stream width is highly variab…
