Effect of Unstable Water Flow on Grain Transport: Insights From Laboratory Experiments Under Reduced Atmospheric Pressure

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Nowadays, Mars presents an environment characterized by low atmospheric pressure (∼6 mbar), which profoundly alters water‐driven surface processes known from Earth. Under these conditions, water rapidly boils, cools, and stabilizes near the triple point, often freezing, which strongly limits its ability to transport sediment.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 1: Laboratory Experiments

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Surface grain size in gravel‐bed rivers is inherently heterogeneous, with marked spatial variability that remains challenging to predict, even in the presence of regular bedforms. This study investigates surface grain size variability on self‐formed alternate bars at the scale of a single bar unit, and is divided in two parts.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 2: Linear Theory

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract This is the second of two papers aimed to investigate grain sorting patterns associated with the formation of steady alternate bars in gravel‐bed rivers. Part 1 presented the analysis of a series of tailored experiments, performed in a mobile bed laboratory flume with fixed, straight banks. The results showed that a consistent pattern of grain

Modeling the Anthropogenic Effects on Watershed Evolution Trajectory: An Example From the Chestatee River in Northern Georgia, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Human activities shape erosion dynamics and landscape evolution, making effective modeling approaches essential for understanding these impacts. This study utilizes landscape evolution models with a streamlined parameterization process to evaluate the anthropogenic effects on the erosional trajectory of the Chestatee River watershed in ...

Controls on Valley‐Floor Width in the Western Andes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce
