Flexible patchy vegetation in a meandering bend: Effect on main flow and dispersion processes
Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.The presence of finite flexible and submerged vegetation patches in bends alters the typical curvature‐induced circulation motion and the streamwise velocity distribution, determining a fragmented flow patternThe lateral dispersion and the mass exchanges are strongly influenced by the vegetated patches and turbulent structures forming in patch‐adjacent

Long Wave Flow Interaction with a Single Square Structure on a Sloping Beach
Journal of Marine Science and Engineering, 2015 In the context of dam breaks, tsunami, and flash floods, it is paramount to quantify the time-history of forces by the rapidly transient flow to vertical structures and the characteristics of the induced flow patterns. To resemble on-land tsunami-induced

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit
Annalen der Physik, Volume 538, Issue 1, January 2026.The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

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.
