Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Facies analysis provides new insights into event bed deposition in a hadal trench environment
Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Investigation of empennage buffeting [PDF]
Theoretical methods of predicting aircraft buffeting are reviewed. For the buffeting due to leading edge vortex breakdown, a method is developed to convert test data of mean square values of fluctuating normal force to buffeting vortex strength through ...

Effects of Multistage Geotechnical Erosion on Dynamic Mechanical Response of Buried Pipelines
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.River‐spanning pipelines are prone to serious hazards during flooding events, which can trigger erosion, exposure, and large‐scale flotation. In this research, a numerical simulation framework was developed using smoothed particle hydrodynamics (SPH) to analyze the dynamic behavior of pipelines subjected to dam‐breach flood scenarios.

Linearized Three‐Dimensional Planing in Deep and Shallow Water
International Journal for Numerical Methods in Engineering, Volume 126, Issue 23, 15 December 2025.ABSTRACT The traditional analysis of three‐dimensional planing is studied in detail using potential‐flow theory together with linearized free‐surface conditions. The work is extended here to the case of water of finite depth. The planing surface is modeled as a traveling pressure distribution.
