The clogging of a stream bed has a significant impact on the exchange of water between a
river and groundwater, known as hyporheic exchange. Clogging issues in orifices …

The concrete made with different manufactured sands can exhibit complex rheological
properties. The prediction of viscosity is crucial in concrete placement, but remains …

Global climate change has been intensifying the scale and frequency of rock‐ice
avalanches and similar catastrophic mass movements in high‐mountain regions. The …

Rock-ice avalanches are rapid, catastrophic mass flows consisting of massive rock and ice
particles in alpine regions. Varying material properties of rock and ice particles cause them …

Slurry infiltration clogging commonly occurs in porous media with fine pores. This infiltration
leads to changes in the mechanical properties of the matrix, causing challenges such as …

The behaviour of granular column collapses is associated with the dynamics of geohazards,
such as debris flows, landslides and pyroclastic flows, yet their underlying physics is still not …

Granular systems, no matter whether they are dry or saturated, are commonly encountered
in both natural scenarios and engineering applications. In this work, we tackle the …

抄録 We perform a series of quasi-static simple shear tests on samples of superdisks using
the level set discrete element method (LS-DEM). We then define the shapeinduced clusters …

We present a length-scale-based rheology for dense sheared particle suspensions as they
transition from inertial-to viscous-dominated. We derive a length-scale ratio using …

Refractive index matching (RIM) is widely used to investigate particle-liquid mixture flows.
However, determining the volume fraction φ in RIM is generally empirical and lacks …
