Non‐Linear Hillslopes Produce Apparent Non‐Linear River Erosion Models

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Non‐linear relationships between catchment‐wide erosion rate and normalized channel steepness within fluvial basins are commonly interpreted to indicate that river erosion is proportional to river slope raised to a power greater than one. This interpretation has crucial implications for the inferred erosion model and for our ability to extract

Synchronous Advance of the Alpine Glaciation Across the Northern and Southern Tibetan Plateau During the Mid‐Pleistocene Transition

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Morphological Dating of Fluvial Terrace Risers Across Spatial and Temporal Scales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fluvial terraces are valuable terrestrial records of past climatic and tectonic changes. Morphological dating, which quantifies the degradation of the riser between two terraces, offers a relatively simple and cost‐effective alternative to other dating methods.

Emission Characteristics of PCDD/Fs, Heavy Metals, and Nuclides during Incineration of Waste Resins Containing Nuclides

Aerosol and Air Quality Research
The waste resins generated from nuclear power plants contain radioactive substances, such as 137Cs and 60Co. The treatment of nuclear power plant waste resins is more challenging compared to conventional resins.

Radionuclide Transport in Fractured Rock: Numerical Assessment for High Level Waste Repository

Science and Technology of Nuclear Installations, 2013
Deep and stable geological formations with low permeability have been considered for high level waste definitive repository. A common problem is the modeling of radionuclide migration in a fractured medium. Initially, we considered a system consisting of
