Currents can affect the evolution of waves in nearshore regions through altering their wavenumber and amplitude. Including the effect of ambient currents (e.g., tidal and wind-driven) on waves in phase-resolving wave models is not straightforward as it requires appropriate boundary conditions in combination with a large domain size and long...

Wave height attenuation in vegetation canopies is often all attributed to the drag force exerted by vegetation, whereas other potential dissipation process is often neglected. Previous studies without vegetation have found that opposing currents can induce wave breaking and greatly increase dissipation. It is not clear if similar process may...

Observations from wave basin experiments and wave-resolving numerical simulations demonstrate the effect of wave-current interaction on shear stress around a sandy mound. Observations from the wave basin show that the mound deformation rate and morphological patterns depend on the mixture of waves and currents in the incident flow conditions....

In numerical ocean models, the effect of waves on currents is usually expressed by either vortex-force or radiation stress representations. In this paper, the differences and similarities between those two representations are investigated in detail in conditions of both conservative and nonconservative waves. In addition, comparisons between...

Over recent decades, the exploitation of wave energy resources has sparked a wide range of technologies dedicated to capturing the available power with maximum efficiency, reduced costs, and minimum environmental impacts. These different objectives are fundamental to guarantee the development of the marine wave energy sector, but require also...

This study presents the results of small scale flume experiments on a submerged rectangular cylinder subjected to a current, regular wave and combined wave-current environment. The objective of the study is to gain more knowledge about the hydrodynamics around and the kinematics of a submerged structure, to give a contribute to the research...

Coastal vegetation is efficient in damping incident waves even in storm events, thus providing valuable protections to coastal communities. However, large uncertainties lie in determining vegetation drag coefficients (C<sub>D</sub>), which are directly related to the wave damping capacity of a certain vegetated area. One major uncertainty is...

In the coastal defence of the Netherlands, sand nourishment is a common practice. Part of the Dutch coastal system, the Wadden Sea coast, is a very complicated coastal system in terms of hydrodynamics and morphodynamics. Many different processes are playing a role in the coastal dynamics in the Wadden Sea area. The execution of a mega...

Tidal flat landscape formation and evolution are closely related to the biotic and abiotic processes that take place in the intertidal environments. Extensive studies have been carried out on the relevant agents such as hydrodynamics, sediment transport and the related ecosystem (vegetation and benthic communities) dynamics. However, the...

Over the last five years a research program has been carried out to assess the performance of the spectral wave model SWAN in the Wadden Sea so that it may be used for the transformation of offshore wave conditions to wave boundary conditions near the sea defenses (dikes and dunes). The assessment was done on the basis of extensive wave...

The present study aims to assess the prediction of wave penetration into tidal inlets under ambient current in SWAN. The performance of SWAN in the modelling of wave-current interaction was studied for two field cases, namely Port Phillip Bay Heads, Australia, and the Amelander Zeegat in the Dutch Wadden Sea. In-situ wave observations were...

The Paintal (1967) formula can be used to estimate transport rates of coarse-grained bed material (such as stones from a bed protection) under low hydraulic loads just above the threshold of motion; the application however is limited to steady currents. This paper presents research aimed at extending the range of application to a combination of...

In this paper a new wave pool concept is presented using ship hulls as wave generators. To evaluate the potential of such a concept a towing tank experiment is conducted to investigate ship wave generation in a confined space. In the towing tank experiment various hull sizes and velocities are examined to maximize the generated wave height. The...

From February to April 1999, wave-blocking experiments have been conducted at the Laboratory of Fluid Mechanics of the Faculty of Civil Engineering and Geosciences, Delft University of Technology, The Netherlands as a part of the Ph.D. research of I.K. Suastika. Wave blocking is a special case of wave-current interaction. It can occur when waves...

Changes in the mean horizontal-velocity profile in combined wave-current motion, outside the bottom boundary-layer, are essential for the correct prediction of cross-shore sediment transport outside the surf zone and the transport of dissolved matter, e.g. Klopman (1992). To be able to verify mathematical and numerical models (see Klopman, 1992)...

The present report contains a description of an experimental program, as a follow up of experiments by v.d. Kaaij and Nieuwjaar in 1986, and Nap and Van Kampen in 1987. As in the second study, in the present study a particle sand diameter of D50 = 100 mu was used, so that the experiments of Nap and Van Kampen will be referred as "the earlier 100...

The interaction of a gravity wave with a steady uniform current is discussed in this paper. Analysis indicates there is no dominant difference in the results obtained when employing either the equation of conservation of wave energy flux or the equation of conservation of wave action flux. Numerical calculations of the wave length change by...

In een modelgoot wordt door het golfschot naast een periodieke golf in het algemeen ook een stoorgolf opgewekt. Aangezien de voortplantingssnelheid van deze golven ongelijk is wordt door niet-lineaire interactie nog een golf opgewekt, de interactiegolf. Daardoor vertoont het totale golfbeeld een ruirntelijke periodiciteit die gekarakteriseerd...

11th Conference on Coastal Engineering in London 1968, the author presented a method for computing the littoral drift starting from the longshore current velocity as this is generated by the waves and with the assumption that the material is stirred up by the waves. In this paper measurements in a model basin are described by which the procedure...

Due to the increased velocity vector in the case of current combined with waves the bottom shear stress in the direction of the current will increase. This increase has been derived and the derivation has been checked by measurements.
