TL;DR: In this article, the wave-induced sediment transport is calculated at prototype scale in the Large Wave Flume (GWK) in Hannover using field measurements and extreme conditions (wave-induced sheet-flow transport).
Abstract: At sandy coasts the sediment transport due to wave action can cause beach erosion and loss of protecting dunes. In order to calculate the wave-induced sediment transport the physical parameter of wave height, waveinduced current, instantaneous sediment concentration and bottom elevation have to be known or measured. The following study was concerned with field measurements and extreme conditions (wave-induced sheet-flow transport), which were simulated at prototype scale in the Large Wave Flume (GWK) in Hannover.

TL;DR: In this paper, a wave tank with simulated steep waves with and without in-line current in which the wave profiles and the corresponding kinematics were simultaneously measured was used to predict the measured wave-current kinematic well.

TL;DR: In this paper, the mass transport velocity in a two-layer system produced by wave action was analyzed, and it was shown that the velocity can be increased one order of magnitude in relation to the velocity given by the rigid bed theory and can be opposite to the wave propagation direction.
Abstract: This paper analyzes the mass transport velocity in a two layers system produced by wave action. In a previous paper, Piedra Cueva (1933), a theory for linear water waves propagating in a two layered viscoelastic fluid system was described. The mass transport in the mud layer and in the water boundary layer is obtained solving the momentum and mass conservation equations in the Lagrangian coordinate system. It was found that the Eulerian coordinate system is not appropriate because it does not guarantee the continuity of the mass transport velocity through the water-mud interface. The results show that the mass transport velocity can be increased one order of magnitude in relation to the velocity given by the rigid bed theory and can be opposite to the wave propagation direction, depending on the physical mud properties. This result is very important when considering near bed sediment transport.

TL;DR: In this article, the authors examined the sensitivity of the load combination factor to various iceberg and wave parameters typical of three sites off the East Coast of Newfoundland, and found that the load factor is most sensitive to the wave angle relative to the current direction, and the wave climate during the iceberg season.
Abstract: The present paper describes an extension to a recent study (Foschi et al, 1996), which was undertaken to determine the appropriateness of the recommended value of the load combination factor relating to the combined effects of wave and iceberg loads, as described in the Canadian Standards Association (1992) code for the design and construction of fixed offshore structures The study examines the sensitivity of the load combination factor to various iceberg and wave parameters typical of three sites off the East Coast of Newfoundland The methodology is based on a numerical analysis in which loads due to waves alone, an iceberg alone, and an iceberg and waves in combination, have been calculated for a range of iceberg and wave parameters, with the results applied to a first-order reliability analysis to study force levels corresponding to specified annual exceedence probabilities The results indicate that the load combination factor is most sensitive to the wave angle relative to the current direction, and to the wave climate during the iceberg season therefore, the load combination factor is site dependent The load combination factor has been calculated as 025 on average, with a conservative value of 033 This compares with the Code values of 08 or 04, for icebergs and waves which are taken to be stochastically dependent or independent, respectively
