High‐Resolution Channel Geometry Reveals Contrasting Styles of Gravel River Adjustment

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Rivers self‐organize to convey water and sediment, giving rise to robust downstream scaling between channel geometry and drainage area, underpinning landscape evolution models. However, these relations rely on limited observations per watershed. We quantify downstream changes in channel slope and bankfull width for six gravel rivers.

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

A Novel Soil Chronometer: Uranium Comminution Ages Measure Soil Production Rates in a Deep Granitic Weathering Profile

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

Beyond Water: Mapping Sediment Bars to Enhance Satellite Monitoring of River Dynamics

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Unvegetated sediment bars are central to river morphodynamics but are rarely used as indicators of channel dynamicity in satellite‐based studies. Linking sediment dynamics and river lateral mobility requires monitoring sustained changes in both water and sediment—the active channel (AC)—to avoid stage‐dependent noise.

Artificial Intelligence and Objective‐Function Methods Can Identify Bankfull River Channel Extents

Water Resources Research
Bankfull channel extents are of fundamental importance in fluvial geomorphology, to describe the geomorphic character of a river, and to provide a boundary for further processing of morphologic and hydraulic attributes.

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, Volume 12, Issue 1, February 2026.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

Palaeoglacier reconstruction and dynamics of Cordillera Vilcanota in the tropical high Peruvian Andes

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

One application of mega-geomorphology in education [PDF]

One advantage of a synoptic view displaying landform assemblages provided by imagery is that one can often identify geomorphic processes which have shaped the region and which may affect the habitability of the area over a human life time.

Scour hole behaviour: A field study of the Dutch Rhine Delta

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
Scour hole behaviour can be divided into dynamic and stable. Dynamic scour holes grow in area, depth and volume during seasonal discharge variations and are typically located in discharge‐dominated river reaches. Stable scour holes are found in tidal rivers with heterogeneous riverbeds and show nearly fixed dimensions.
