Sedimentology, EarlyView.ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

An Experimental and Theoretical Study of Wave Damping due to the Elastic Coating of the Sea Surface
Journal of Marine Science and Engineering, 2020 Flexible plates or membranes located on the sea surface can be effective for attenuation waves approaching the beach. The most efficient structures should be found through comprehensive research using developed experiments and theory.

Time-Reversal Generation of Rogue Waves
, 2014 The formation of extreme localizations in nonlinear dispersive media can be explained and described within the framework of nonlinear evolution equations, such as the nonlinear Schr\"odinger equation (NLS).

Cliff retreat and sea bed morphology under monochromatic wave forcing: Experimental study [PDF]
, 2011 Wave flume experiments have been performed to investigate a sandy cliff recession under monochromatic wave forcing. We varied the wave climate through the wave energy flux F and the surf similarity parameter j.

Sedimentology, EarlyView.ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Is the critical Shields stress for incipient sediment motion dependent on channel-bed slope? [PDF]
, 2008 Data from laboratory flumes and natural streams show that the critical Shields stress for initial sediment motion increases with channel slope, which indicates that particles of the same size are more stable on steeper slopes.

Investigation on Flow Resistance of Large‐Scale Channels With Unmanaged Spontaneous Vegetation
Hydrological Processes, Volume 40, Issue 5, May 2026.The hydraulic measurements of two surveys (November 1995 and June 1996) by Flippin‐Dudley et al. were used. A theoretical flow resistance equation was assessed for a large‐scale vegetated channel. The analysis demonstrated that the theoretical flow resistance equation allows an accurate estimate of the Darcy–Weisbach friction factor.

Insights Into the Dynamics of Vegetated Alternate Bars by Means of Flume Experiments
Water Resources Research, 2023 Alternate bars are bedforms recognizable in straight or weakly curved channels as a result of riverbed instability. The length and height of alternate bars scale with the river width and the water depth, respectively.

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance
