TL;DR: In this paper, the motion of spherical particles (diameter 1.58 mm, specific gravity 2.5) on 2 and 3% plane slope was studied in a laboratory wave flume for shoaling wave conditions.
Abstract: The motion of spherical particles (diameter 1.58 mm, specific gravity 2.5) on 2 and 3% plane slope was studied in a laboratory wave flume for shoaling wave conditions. The range of wave-height-to-water-depth ratio was 0.24

TL;DR: In this paper , the authors investigated the transient fluid motion within a narrow gap formed by two fixed boxes suffered from incident focused wave groups using a two-dimensional viscous flow numerical wave flume and the response/damping time of the transient wave surfaces inside the gap, the maximum wave forces and the ratios of the 2nd-order to the corresponding 1st-order wave surfaces/forces.

TL;DR: In this article, the authors present a simple, practical formulation to evaluate bed shear stresses and bedload transport rates due to asymmetric and skewed waves plus a current in an oscillating water tunnel, based on fitting the exact results of a rigorous, analytical model of the OWT wave-current boundary layer.
Abstract: Experimental studies of sediment transport rates due to nearshore waves are often conducted in oscillating water tunnels (OWTs). In an OWT, the oscillatory motion produced by the piston propagates almost instantaneously along the entire tunnel. Consequently, unlike the wave motion in the sea or in a wave flume, flow in an OWT is uniform along the tunnel, and second-order wave propagation effects (such as Longuet-Higgins's streaming) are absent. The effect of these hydrodynamic differences between OWT and sea waves on sediment transport rates has generally been neglected. In this paper we present a simple, practical formulation to evaluate bed shear stresses and bedload transport rates due to asymmetric and skewed waves plus a current in an OWT, based on fitting the exact results of a rigorous, analytical model of the OWT wave-current boundary layer. By then accounting for real wave effects we find that wave propagation significantly affects the predicted period-averaged net sediment transport rates. Such real wave effects can therefore not be neglected when comparing nearshore transport models with OWT data.

TL;DR: In this paper, a 1:5 true scale reinforced concrete highway bridge superstructure specimen was constructed and is now being tested under regular and random waves with different wave parameters in a 104 m long wave flume.
Abstract: Recent failures of coastal highway bridges during hurricane events have shown the need for improved modeling and analysis of storm induced wave forces. The damage was attributed to elevated storm surges that enabled larger waves to reach the superstructure and in some cases remove it. Presented is a new large-scale laboratory setup that enables direct measurement of storm induced wave forces on bridge superstructures. A 1:5 true scale reinforced concrete highway bridge superstructure specimen was constructed and is now being tested under regular and random waves with different wave parameters in a 104 m long wave flume. The bridge specimen is instrumented with pressure transducers, strain gages, and six load cells to measure overall horizontal and vertical forces. The stiffness of the horizontal support system can be varied to represent different dynamic properties of the bridge substructure. The experiments will provide needed large-scale data for wave induced forces on coastal highway bridges and permit comparison with existing design and analysis methods. First experiences and a set of preliminary measurements are presented and discussed.

TL;DR: In this article, the authors analyzed the difference between the method proposed by Kweon et al. (2011) and the wave force measured at a different time without a phase difference, by measuring wave pressure acting on a breakwater model.
