TL;DR: In this paper, the transformation of water waves generated in a numerical wave flume is investigated, and the results show that short waves agree well with the linear solutions, whereas the long waves with limited Ursell numbers are consistent with the analytical solutions.

20 May 1991TL;DR: In this paper, a study of littoral sediment transport rate based on three-dimensional hydraulic model experiments performed with regular and irregular waves is described, and an expression is developed linking sediment transport rates to wave steepness, beach slope, relative grain size and breaking angle.
Abstract: This paper describes a study of littoral sediment transport rate based on three-dimensional hydraulic model experiments performed with regular and irregular waves. Deep water wave conditions, wave heights through the surf zone, wave breaking angles, longshore current velocity distribution and the bed load and suspended load sediment transport distributions were measured simultaneously to form a coherent data set. An expression is developed linking sediment transport rate to wave steepness, beach slope, relative grain size and breaking angle. The expression compares well with published field data.

TL;DR: In this paper, a series of 63 experiments were conducted in a physical model of a breakwater in a 2D wave flume, which were used to investigate the effect of the wave properties as well as the geometrical characteristics of the flushing culvert placed on breakwaters.

TL;DR: A series of experimental tests on a 2D movable-bed physical model of the protected sandy beach of Gabicce Mare, on the central Adriatic Sea in Italy, is described in this paper.
Abstract: A series of experimental tests on a 2D movable-bed physical model of the protected sandy beach of Gabicce Mare, on the central Adriatic Sea in Italy, is described. Three emerged and three submerged configurations of rubble-mound detached breakwaters, for beach protection, placed at different positions, were tested in the Ancona (Italy) wave flume and the obtained results were compared with those found for a structure-free configuration. Both wave dissipation and reduction of beach erosion efficiency under various wave conditions were obtained and, in particular, the short-term hydro-morphodynamic response of the different tested breakwater configurations.

Coconut Creek (Florida), ISSN 0749-0208.Coastal sand dune system is important in the nearshore environment for sand supply, ecosystem, and hazard mitigation. In this study, a process-based morphological model was performed and the results were compared with large-scale laboratory experimental data. Two-dimensional large-scale laboratory experiments were conducted with 1:6 geometric scale in the large wave flume (104m (L) × 3.7 m (W) × 4.6 m (D)) of the Hinsdale Wave Research Laboratory at Oregon State University (Maddux et al, 2006). Several different wave conditions were used with different water levels in this experiment including pre-storm, storm, and post storm based on random wave time series by using TMA spectrum. The data set included cross-shore Wave heights, fluid velocities, and the profile changes of the beach and dune. The process based model, XBeach (Roelvink et al., 2009) was used to simulate the nearshore hydrodynamics and bed level change during storm wave condition. Several semi-empirical parameters were used in the XBeach model to predict morphodynamic process (Roelvink et al., 2009) and recently the updated parameters (WTI settings) were suggested based on the results of field observations. The present study ran the XBeach model by using both default and WTI settings and compared with the results from the experiments. The results showed that the model results with WTI settings showed good agreement with the measured beach profile while the model results with default settings over-predicted the offshore sediment transport and dune erosion. Especially, the wave skewness (facSk) and asymmetry (facAs) gave the highest contribution to predict dune erosion.
