Soil Freeze–Thaw Disturbance Index and Its Indicative Significance on the Qinghai–Tibet Plateau

Remote Sensing
The soil freeze–thaw process is a dominant disturbance in the seasonally frozen ground and the active layer of permafrost, which plays a crucial role in the surface energy balance, water cycle, and carbon exchange and has a pronounced influence on ...

Quaternary Climate Oscillations Shape Genetic Diversity and Spatial Structure of Viola hybanthoides (Violaceae) Endemic to Danxia Landscape

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We adopted ddRAD‐seq and chloroplast genome sequencing to explore the genetic characteristics of the danxia‐endemic species Viola hybanthoides. This species exhibits extremely low within‐population genetic diversity and obvious genetic differentiation, which is mainly driven by habitat fragmentation, restricted gene flow and Quaternary climatic changes.

Assessment of basin-scale geomorphic processes based on the analysis of longitudinal profiles: A case study of the Dwarkeswar river, Eastern India

Geology, Ecology, and Landscapes
The longitudinal profile of the river bears geomorphic signature of long-term fluvial adjustment to tectonic, structure, lithology, and climate. Therefore, analysis of the longitudinal profile can be helpful in understanding the fluvial process and the ...

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Crustal Thickness Inversion From Magmatic Geochemistry Reveals Spatiotemporal Evolution and Two‐Stage Uplift of the Iranian Plateau

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Cenozoic topographic growth of the Iranian Plateau, situated at the Arabia‐Eurasia collision front, provides insights into continental collision dynamics. However, the relative contributions of tectonic shortening versus deep mantle processes to crustal thickening remain debated because systematic quantitative constraints on paleo‐crustal ...

Seismic Insights Into the Role of Rockfall in Rockslide Destruction Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The dynamic link between rockslide failure and rockfall activity remains elusive, primarily due to the challenge of detecting weak signals amidst high noise. We propose a seismic attribute guided deep learning framework that formulates rockfall detection as a time‐series segmentation task, facilitating the precise extraction of rockfall events

Geomorphic Evolution of the Nushki Segment of the Chaman Fault in Western Pakistan [PDF]

, 2018
The Chaman strike-slip fault marks the western boundary of the collision zone between the Indian and Eurasian plates. It accommodates both lateral translation and convergence of the Indian plate beneath the Eurasian plate and connects the Makran ...

Estimating Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) From River Morphology Characteristics

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT This study demonstrates that flow resistance in rivers, quantified via calibration of a modified Manning's equation, can inform its estimation from channel hydrometric information available from regional or global datasets for a limited set (N = 14) of rigorously calibrated river reaches in Alaska and with less certainty in a large set (N ...

Geomorphic classifiers for flood-prone areas delineation for data-scarce environments [PDF]

, 2017
Knowing the location and the extent of the areas exposed to flood hazards is essential to any strategy for minimizing the risk. Unfortunately, in ungauged basins the use of traditional floodplain mapping techniques is prevented by the lack of the ...

Quantitative analysis of channel characteristics of distributive fluvial systems

Sedimentology, Volume 73, Issue 5, Page 1606-1630, August 2026.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...
