Wave‐Influenced Deltas: Growth Through Cyclical Accretion of Barrier‐Spits and the Role of Mud Open
Wave‐influenced deltas are the most abundant delta type and are also potentially the most at‐risk to human‐caused changes, owing to the effects of wave‐driven sediment transport processes and the relatively short timescales on which they o…

River Avulsion Precursors Encoded in Alluvial Ridge Geometry Open
River avulsions generate catastrophic floods that threaten communities, ecosystems, and infrastructure worldwide. Alluvial ridges—elevated regions of near‐channel topography—are thought to precede avulsions, yet their spatial patterns and …

Assessing Channel Bank‐Height Adjustments and Flood Frequency Trends in a Dynamic Channel‐Levee Evolution Model Open
Natural levees form through sediment delivery from channels, dispersal onto floodplains, and storage at channel margins. When levees breach, they release water and sediment onto the floodplain, occasionally causing river avulsions. Despite…

Topographic Roughness as an Emergent Property of Geomorphic Processes and Events Open
Earth's terrestrial surfaces commonly exhibit topographic roughness at the scale of meters to tens of meters. In soil‐ and sediment‐mantled settings topographic roughness may be framed as a competition between roughening and smoothing proc…

Coastal Wetlands in the Anthropocene Open
We review the functioning and sustainability of coastal marshes and mangroves. Urbanized humans have a 7,000-year-old enduring relationship to coastal wetlands. Wetlands include marshes, salt flats, and saline and freshwater forests. Coast…

Stratigraphic architecture of fluvial fans shaped by downstream changes in avulsion style Open
Natural river diversion, or avulsion, controls the distribution of channels on a floodplain and channel sandstone bodies within fluvial stratigraphic architecture. Avulsions establish new flow paths and create channels through several reco…

Four Years of Meander‐Bend Evolution Captured by Drone‐Based Lidar Reveals Lack of Width Maintenance on the White River, Indiana, USA Open
Meandering rivers experience fluctuations in width whenever riverbanks migrate in different directions or at different rates, which can be observed after individual floods. However, meandering rivers maintain approximately constant widths …

Quantifying landscape change following catastrophic dam failures in Edenville and Sanford, Michigan, USA Open
Dam failures due to changing hydroclimate and ageing infrastructure pose a significant threat to downstream river systems and communities. The detailed geomorphic effects of catastrophic dam failures are not well known because of a lack of…

Topographic Roughness as an Emergent Property of Geomorphic Processes and Events Open
Topographic roughness is a popular yet ambiguous metric used in surface process research for many applications that indicates something about the variation of topography over specified measurement intervals. In soil- and sediment-mantled s…

Machine Learning Predictions of Vertical Accretion in the Mississippi River Deltaic Plain Open
Deltaic landscapes consist of vast wetland systems that rely on sedimentation to maintain their elevation and ecological communities against relative sea‐level rise. In the Mississippi River Deltaic plain, rising relative sea level and ant…

Remotely sensed <span>land‐cover</span> change and floodplain disturbance following <span>upstream‐migrating</span> river avulsions in tropical rainforests Open
The displacement of a river to a new position within its adjacent floodplain is called avulsion, and here we examine how a newly recognized style, called retrogradational avulsion, affects the surrounding floodplain in tropical rainforests…

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…

River Delta Morphotypes Emerge From Multiscale Characterization of Shorelines Open
Delta shoreline structure has long been hypothesized to encode information on the relative influence of fluvial, wave, and tidal processes on delta formation and evolution. We introduce here a novel multiscale characterization of shoreline…

Hillslope roughness reveals forest sensitivity to extreme winds Open
Windthrow, or the uprooting of trees by extreme wind gusts, is a natural forest disturbance that creates microhabitats, turns over soil, alters hydrology, and removes carbon from the above-ground carbon stock. Long recurrence intervals bet…

A global open-source database of flood-protection levees on river deltas (openDELvE) Open
Flood-protection levees have been built along rivers and coastlines globally. Current datasets, however, are generally confined to territorial boundaries (national datasets) and are not always easily accessible, posing limitations for hydr…

First‐Order River Delta Morphology Is Explained by the Sediment Flux Balance From Rivers, Waves, and Tides Open
We present a novel quantitative test of a 50‐year‐old hypothesis which asserts that river delta morphology is determined by the balance between river and marine influence. We define three metrics to capture the first‐order morphology of de…

A method to detect abrupt shifts in river channel position using a Landsat‐derived water occurrence record Open
The lateral migration of river channels is an important control on the evolution of alluvial fans, deltas, and floodplains. Lateral migration consists of both gradual riverbank migration and abrupt shifts in location due to avulsions or cu…

The push and pull of abandoned channels: how floodplain processes and healing affect avulsion dynamics and alluvial landscape evolution in foreland basins Open
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 occur and th…
