Particle motion in the near bed region of a turbulent open channel flow: Implications for bedload transport by saltation and sediment entrainment into suspension
… namely the mode of transport denoted as saltation, and the process of particle entrainment into suspension. The main approach followed is experimental, using visualization and particle tracking techniques to study particle motion and its interaction with near wall turbulence. A high-speed …

On naturalistic saltation genealogies of content: an exploration of continuity & discontinuity in nonreductive diachronic explanations of content by Adam H. Schroeder supervised by University of Cape Town
… name accounts fitting this strategy Naturalistic Saltation Genealogies of Content. Despite the benefits this strategy affords in avoiding the perennial objections naturalisation projects face in relation to normativity, my aim is to show that it is susceptible to its own set of difficulties due to …

Definizione di una metodologia integrata per la stima delle emissioni di PM da superfici di materiali granulari esposte all’erosione eolica
… model implemented in MATLAB, which simulates the saltation, impact, and release of fine particles generated by the saltation process, using as input data the results of experimental analyses preliminary performed on the materials under investigation. The PM10 emissions estimated through numerical …

Feedback between erosional morphology, sediment transport and abrasion in the transient adjustment of fluvial bedrock channels
… evolving channel morphology. Predictions of the saltation-abrasion model (Sklar and Dietrich, 2004) for sediment flux-dependent channel incision guide our efforts although the results are not model dependent. In channels where the dominant incision process is sediment abrasion, sediment transport …

The sedimentology of diamondiferous deflation deposits within the Sperrgebiet, Namibia
… mm) in diameter are commonly entrained into the saltation load above stone pavement surfaces, making this an extremely active aeolian environment.

ASSESSING THE EMOTIONAL DIMENSIONS OF THE CUTANEOUS-RABBIT EFFECT USING FACES
… how emotional images affects tactile saltation. More specifically, we combined visual faces with three different emotions: angry, sad and happy with a tactile illusion known as the cutaneous rabbit effect (CRE) that was delivered on participants’ shoulder at different durations. …

Modelling of radioactive particle resuspension after a dirty bomb event
… in the Regional CFD model to capture particle saltation, enhancing resuspension predictions' accuracy, and introducing a multilayer resuspension model. This study underscores the complex nature of Dirty Bomb scenarios, emphasizing the need for a holistic understanding that combines experimental …

Mechanisms of Sediment Entrainment and Transport in Rotorcraft Brownout
… or "splash." The classical process of saltation bombardment was also visualized for larger particles whose inertia prevented them from being suspended in the vortical flow. While providing new insight into the time- and length-scales associated with sediment transport by a rotor wake, …

Multiscale environmental flow dynamics: particle settling, turbulence modulation, and tornadic vortices
… the flow characteristics that ultimately govern saltation and debris entrainment in atmospheric storms. The experiments and setups establish a multiscale framework that links inter‑particle hydrodynamics, rheology‑controlled turbulence, and coherent‑vortex structure. The scaling laws and …

Biogenic buildups and carbonate sedimentation, Dry Tortugas Reef Complex, Florida
… surface creep population, sand-sized saltation population and very fine sand-to silt-sized suspension population. Strong mixing occurs between the gravel and sand population on the storm-degraded shoals, and between the sand and silt population on the lagoon bottom. Sands flanking the …

Design and prototyping of a test facility to investigate the transport properties of dilute phase gas-particle flows applicable to coal-fired power plants
… will be suitable to conduct pressure drop tests, saltation and choking tests, as well as mass balances and visual observations. The process model and methodologies developed here may now be applied in the detail design and operation of such a final test facility.
