This study introduces a new workflow for estimating surface grain size in paraglacial and periglacial environments using drone photogrammetry and machine learning. Trained on Canadian alpine basins and validated on an Italian rock glacier, the model demonstrates high efficiency and accuracy, providing a new tool for studying these landscapes.

The invasion and treatment of Russian olive imposed distinctive geomorphic effects along the Escalante River, Utah, USA. Because this invasion was progressive and superimposed upon an on-going, multi-decadal channel narrowing involving native vegetation, resulting channel change was spatially and temporally complex with upstream to downstream differences in channel response.

Sand ridges, typically found on tide- and storm-dominated shelves, are documented for the first time in a semi-enclosed bay of a non-tidal intra-continental sea. High-resolution hydroacoustic data reveal their morphology, internal structure and varying preservation states, providing new insights into their formation and evolution in the southern Baltic Sea.

Quantitative geomorphology analyses reveal spatial variation in landscape characteristics across fault zones, suggesting differential fault activity and uneven uplift of geological units in the North Qilian Shan, providing new insights into the northeastern expansion of the Tibetan Plateau.

This study reveals the tectono-climatic coupling in orogenic evolution: ratio of shortening rate to rainfall rate (RSR) positively regulates drainage density; climate shifts erosion from lateral to headward dominance, while tectonics govern topography and climate modulates sedimentation, validated by natural systems like Longmen Shan.

Increasing bed slope, decreasing wall slope, increasing blowout width, decreasing wind speed and increasing wind angle result in a decrease in average shear velocity on the lateral walls and bed surface of the blowout, which then facilitates blowout stabilisation.

This study has identified constructed foredune notches and using aerial images created a classification system based on morphometric measurements of 133 notches in four countries. Six classifications are proposed: A—Minor notch, B—rectangular notch, C—slot and lobe, D—trapezoidal notch, E—elongated notch, and F—composite notch.

During mechanical wetting, the pore water gradually encroaches on the pore structure, which increases the debonding effect and the loess behaviour gradually converges to that of saturated loess. The compression of pore makes the increased saturation insufficient to offset the enhancement of capillary action, thus strengthening the water retention property.

In this study, we demonstrate that coarse-grained bar edges, referred to as “lateral lag deposits”, play a key role in stabilizing non-vegetated gravel-cobble bars, particularly during lower-discharge flooding events. We also describe the morphology of these gravel-bar structures in a braided-wandering stream.

Despite TLS providing displacement data with less noise and internal distortion, SfM photogrammetry using ground-based cameras can achieve comparable performance for sinkhole characterization and monitoring in an urban area if accurate geodetic data are available. However, both techniques may underestimate the extent and rate of the deformation.

Rare earth elements show aeolian sediment in the Taklimakan Desert mainly comes from the West Kunlun Mountains, with similarity to desert due to river and wind regime.

Landscapes of thrust belts coevolve with carbonate aquifers controlled by base-level dynamics linking surface-subsurface processes. Increments of Neogene uplift and slip rates, erosional unroofing, speleogenesis, exhumation of caves and origin of aquifers are recorded by landforms. 3D–4D geo-modelling of carbonate aquifers may be constrained to coevolution history of landscape and subsurface.

At Baishui River Glacier No. 1 in Yulong Snow Mountain, even if the horizontal and vertical velocities are accurately measured, the large uncertainties related to the slope changes prevent us from calculating the point surface mass change from the emergence velocity.

This study proposed a 2D numerical model considering multi-layered, non-uniform sediments to simulate the failure of the second Baige landslide dam. The effects of upstream inflow and dam material composition are investigated. The model outperformed empirical and simplified approaches, providing a more reliable simulation framework that aids to hazard management in mountainous regions.
