Review on Bougue gravity anomaly and crustal density structure in Sichuan-Yunnan and its adjacent areas

地球与行星物理论评, 2022
Sichuan-Yunnan and its adjacent area are the main places where the eastward material flow from the Tibet Plateau escapes and spins to SE-SSE with active geological formations and frequent seismic activity.

Predicting Head Loss and Hydraulic Roughness of Channel‐Spanning Large Wood Jams

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Log jams enhance hydraulic and geomorphic diversity in river corridors. Channel‐spanning log jams induce backwatering, increase local flow heterogeneity, promote sediment deposition, and improve aquatic habitat diversity. Despite their increasing popularity in river restoration, predicting their hydraulic effects remains a challenge.

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Flow Simulation and Energy Loss Estimation in the Nappe Flow Regime of Stepped Spillways with Inclined Steps and End Sill: A Numerical Approach [PDF]

Civil Engineering Journal, 2016
Recently, the usage of stepped spillways, as energy dissipaters, has increased and led to a reduction in the size of the stilling basin. Extensive experimental considerations, plus the high cost and extended time required for laboratory methods, are among the major issues that require precise attention to determine optimal step design.

Anomalously Low 3He/4He and Elevated Heat Flow in the Northern Apennines Explained by Lithospheric Delamination: A Modeling Approach

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The 3He/4He ratios measured in 12 CO2‐dominated gas seeps from the Tuscany‐Roman Volcanic Provinces in Italy range between 0.07 and ∼1.6 Ra. Helium and δ13CO2 isotope systematics indicate a dominant crustal source with a variable but significantly lower contribution from the mantle.

Block‐in‐Matrix Deformation and Veining in Alpine Subducted Oceanic Metasediments at Blueschist Facies Conditions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle deformation in stiffer bands and blocks.
