Influence of climate and the expansion of C4 grasses on sequence-scale cyclicity and landscape development during the late Miocene to Pleistocene of West Texas.
… a decreasing sedimentation rate, less frequent channel avulsion events, and an increase in paleosol maturity. Stratigraphic stacking-patterns parallel pCO₂ concentration, suggesting that sedimentation and pedogenesis are influenced by third- to fourth-order global climate cycles.

Comparison of Two Potential Streamgage Locations on Scott Creek at Swanton Pacific Ranch, California
… for measuring high flow events; however, the channel is in a state of disequilibrium due to debris jams within the 140 foot reach above the bridge. This site is also problematic due to the occurrence of channel avulsion which is scouring and incising a new channel which threatens to undermine …

Fluvial sequence stratigraphy and paleoclimate of the Upper Triassic (Norian-Rhaetian) Chinle Strata, northern New Mexico.
… the products of autocyclic processes, such as channel avulsion, floodplain aggradation, and channel migration. These results suggest that regionally significant tectonic episodes may be discernible in suspended-load fluvial deposits that accumulated over a broad area. Each location contains …

Sequence Stratigraphic Architecture of Early Pennsylvanian, Coal-bearing Strata of the Cumberland Block: A Case Study from Dickenson County, Virginia
… and autocyclic deltaic processes related to channel avulsion and delta lobe switching.

Anatomy of a Carboniferous transgression: upper Tullig Cyclothem, County Clare, Ireland
… at the top of the fluvio-deltaic sandstone channels of the Tullig Sandstone. At this point, relative sea-level was at its minimum, and the beginning of the transgression is marked by symmetrical dunes, reworked dunes, and Zoophycos trace fossils. This surface is overlain by nearly 20 meters …

Vulnerability of Coal- and Natural Gas-Fired Power Plants to Climate Change
… can develop from autogenic interactions (e.g., channel avulsion and delta lobe switching). In this work, we are interested in understanding how traditional, allogenically-based interpretations of these systems change when we incorporate the impacts of autogenic processes. We introduce a novel …

Fluvial geomorphology and paleofloods in arid central Australia
… mechanisms of flood plain destruction are channel widening, flood plain stripping, swirl pit,flood and back channel scour. The principal mechanisms of flood plain construction are the deposition of insets, flood plain veneer, channel and whirl pit fill, channel abandonment and the formation …

Influences of Channel Dredging on Avulsion Potential at the Atchafalaya River
… from the Mississippi River to its distributary channel; the Atchafalaya River. If not prevented by man-made structures, the complete capture of the Mississippi River by the Atchafalaya River was predicted. The USACE report cites multiple causes for the observed increase in discharge …
