TL;DR: In this article, the authors implemented and tested the new SANTOSS sand transport formula with the cross-shore morphodynamic model UNIBEST-TC using data from the LIP and Grasso wave flume experiments.
Abstract: In this paper, we have implemented and tested the new SANTOSS sand transport formula with the cross-shore morphodynamic model UNIBEST-TC using data from the LIP and Grasso wave flume experiments. It is shown that the total net sand transport is a delicate balance between wave- and current-related transport in the wave boundary layer (which can be on- or offshore-directed) and offshore-directed current-related suspended load above it. The change from onshore to offshore net transport for the two Grasso cases was reproduced by the SANTOSS model and seems to be due to the increasing importance of phase-lags between intra-wave velocities and sand concentrations. More generally, measured net sand transport rates are reasonably well reproduced by the SANTOSS formula outside the surf zone if orbital velocities and ripple heights are predicted correctly and phase-lags between velocities and suspended sand concentrations are accounted for.

TL;DR: In this paper , a new type of free surface breakwater is proposed for the purpose of wave attenuating in regular waves, which is made up of two parts: the rigid main body of a rectangle box piercing through the free surface, and the appendage structure with double flexible membranes hanging below the rectangle box.

TL;DR: In this paper, the results of experiments on heavily roughened cylinders in regular waves and linear oscillatory flow at Reynolds numbers in the range from 6x10E4 to 7.7x10 E5 and Keulegan Carpenter numbers from 1 to 29 were described.
Abstract: This paper describes the results of experiments on heavily roughened cylinders in regular waves and linear oscillatory flow at Reynolds numbers in the range from 6x10E4 to 7.7x10E5 and Keulegan Carpenter numbers from 1 to 29. The first set of experiments used a 521mm diameter vertical cylinder in the Delta wave flume of the Delft Hydraulics Laboratory. The second set of experiments used a 420mm diameter vertical cylinder mounted on a new underwater linear oscillatory carriage facility at the Marine Technology Centre of the University of Strathclyde. The experimental arrangements are described in both cases.

TL;DR: In this article, a 58.04m wave flume has been constructed and calibrated, and a series of tests performed to verify design curves presented by Gilbert, Thompson, and Brewer show good agreement with the predicted values.
Abstract: A 58.27 × 4.57 × 3.04 m wave flume has been constructed and calibrated. The maximum wave height that can be generated in regular waves is 0.7 m at a water depth of 1.8 m. Random wave spectra have also been modelled in the flume for prototype wind speeds up to 25 m/s. The maximum significant wave height that can be generated at a 1 m water depth is 20 cm.A series of tests performed to verify design curves presented by Gilbert, Thompson, and Brewer show good agreement with the predicted values. The Pierson-Moskowitz spectrum was modelled between wind speeds of 5 and 25 m/s at suitable scale factors ranging from 1:50 to 1:150. All analysis was carried out in real time by means of an on-line computer.
