Hydraulic Control of Fish Distribution at Large River Confluences: Evidence for Cross‐Sectional Flow Organization

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Confluences are among the most hydrodynamically complex environments within fluvial networks and are widely recognized as ecological hotspots. Effective management of fish assemblages in such systems requires a mechanistic understanding of hydrodynamic‐ecological coupling.

Radial and vertical angular momentum transport in protostellar discs [PDF]

, 2007
Angular momentum in protostellar discs can be transported either radially, through turbulence induced by the magnetorotational instability (MRI), or vertically, through the torque exerted by a large-scale magnetic field.

Joint short-term prediction of polar motion and length of day with multi-task deep learning methods

Earth, Planets and Space
Accurate prediction of Earth orientation parameters (EOPs) is critical for astro-geodynamics, high-precision space navigation, and positioning. However, the current model prediction accuracy for EOPs is significantly lower than the geodetic technical ...

Tropical Ocean Evaporation‐Temperature Sensitivity to Surface Radiative Property Perturbations in Fully Coupled CESM2

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Tropical ocean evaporation is the dominant source of moisture for global precipitation. However, the dependence of evaporation‐temperature sensitivity on ocean surface radiative properties has not been quantified in the fully coupled modeling framework.

How Terrain Geometry and Environmental Instability Shape Precipitation in Mountain‐Crossing Mesoscale Convective Systems

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract This study uses idealized large‐eddy simulations to systematically examine how terrain geometry and environmental instability modulate precipitation produced by a mountain‐crossing mesoscale convective system (MCS). A suite of simulations isolates the effects of base‐state convective available potential energy (CAPE), mountain width, and crest

Geophysical Fluid Contributions to Intradecadal Length of Day Variations

Edinburgh Student Journal of Science
Variations in length of day (LOD) are a result of mass movements in the Earth's fluid envelope and deep interior. Previously, a six (SYO) and eight year (EYO) oscillation have been inferred to arise from fluid motions in the core; however, these signals ...

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

River, Volume 5, Issue 3, Page 432-452, August 2026.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

A review of the research and advancements in MSDF monitoring for the remote sensing of soil and water conservation in China

River, Volume 5, Issue 3, Page 351-368, August 2026.
Abstract With the advancement of remote sensing technology, the accuracy of satellite remote sensing data has continuously improved, and the precision of large‐scale soil and water conservation monitoring has steadily increased. However, owing to differences in sensor acquisition and processing methods, monitoring data obtained through various ...

Well‐Posed Debris‐Flow Models With Phase Separation

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Debris flows pose a severe hazard to people and infrastructure in mountainous regions and are prone to phase separation. This can be captured by the depth‐averaged multiphase theory of Meng et al. (https://doi.org/10.1017/jfm.2022.400), which accounts for vertical structure, velocity shear, and relative motion between the grains and fluid.

Role of Barystatic Sea Level Change in Global Mass Conservation and Its Excitation to Length‐Of‐Day Variations

Earth and Space Science
Barystatic sea level stores excess water mass from the atmosphere and land to maintain global mass conservations within the Earth system. Besides the secular contribution to global sea‐level rise, changes in barystatic sea level also play an important ...
