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.

Using Environmental Variables for Studying of the Quality of Sampling in Soil Mapping

مجله آب و خاک, 2016
Introduction: Methods of soil survey are generally empirical and based on the mental development of the surveyor, correlating soil with underlying geology, landforms, vegetation and air-photo interpretation.

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 ...

Tectonic geomorphology of Türkiye and its insights into the neotectonic deformation of the Anatolian Plate

Earthquake Research Advances
Quantitative geomorphic analyses are usually powerful in identifying active tectonics across global orogenic belts. Our present study will focus on the Anatolian Plate which hosts a lot of recent catastrophic earthquakes in Türkiye.

High‐Resolution Satellite Imagery Mapping of the Surface Rupture and Slip Distribution of the Sagaing Fault in the 28 March 2025 Mw 7.7 Earthquake, Myanmar

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract On 28 March 2025, a Mw 7.7 earthquake occurred on the Sagaing Fault in Myanmar. Security constraints prevented timely field investigations on its surface rupture, hindering analysis of seismotectonics and rupture dynamics. Using high‐resolution satellite imagery, we mapped a ∼420 km surface rupture and measured 540 dextral offsets, revealing ...

Comparative geospatial and statistical analysis of DEM-derived geomorphic indices from multiple datasets for assessing relative active tectonics

Geomatics, Natural Hazards & Risk
Tectonic activity plays a vital role in achieving sustainable land management and hazard mitigation in seismically active regions. This study evaluates geomorphic indices derived from four digital elevation models (DEMs), including SRTM, Copernicus, FAB,

The Potential Applications of Optical Dating to the Sandy Uplands of East Texas and Northwest Louisiana [PDF]

, 1998
The fine, sandy soils of East Texas and Northwest Louisiana have been the source of archaeological debate for some time. This discourse concerns the mode of burial of cultural material in the easily eroded soils and the mechanics of recent (Holocene ...

Abrupt Along‐Strike Change of Shallow Seismicity in Central and Southern Myanmar: Insights From High‐Resolution Local‐Earthquake Catalogs and Focal Mechanisms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Myanmar's high seismic hazard is underscored by the 2025 Mw 7.7 earthquake on the Sagaing Fault, yet its seismicity patterns and underlying controls remain poorly understood. Using new seismic data from the 2nd‐phase array of the China‐Myanmar Geophysical Survey in the Myanmar Orogen, we construct a high‐resolution catalog of 1,819 local ...

Phelps Lake and Jim Burt: Two Middle Woodland Period Mounds in Northwestern Louisiana [PDF]

, 2002
Clarence Webb defined the pre-Caddoan Bellevue focus on the basis of investigations at several isolated mounds located in upland settings in northwestern Louisiana. With the exception of the Bellevue Site (16B04), little detailed information is available
