In the following we consider the forcing of long waves by normally or obliquely incident grouped short waves, also known as surf beat. Two mechanisms responsible for the generation of long waves are considered: the release of the bound long waves associated with changes in the spatial variation of the incident short wave energy [Longuet-Higgins...

Only in the last 25 years have coastal engineers begun to come to an understanding of the physical processes in and around tidal inlet systems. This lack of knowledge has caused tremendous surprises and problems due to unanticipated reactions of the system to changes caused by human interference. Examples of such interference are: (partial)...

In this paper the nonlinear numerical model SHORECIRC is applied to simulate the intragravity wave conditions on two days during the 1990 Delilah campaign. In order to simulate the wave conditions an algorithm has been derived which synthesizes a directional of/shore wavefield from data including the bound, directional low-frequency components....

lecture note: Tidal inlets and their associated basins (lagoons) are a common feature of lowland coasts all around the world. A significant part ofthe world's coastlines is formed by barrier island coasts, and most other tidal coasts are interrupted by estuaries and lagoon inlets. These tidal systems play a crucial role in the sediment budget...

The growth rate, shoreline reflection, and dissipation of low?frequency waves are investigated using data obtained from physical experiments in the Delft University of Technology research flume and by parameter variation using the numerical model Delft3D?SurfBeat. The growth rate of the shoaling incoming long wave varies with depth with an...

Recent events like the Sumatra tsunami and Hurricane Katrina have reminded the world of the vulnerability of coastal areas to extreme events. Despite hydraulic engineering measures to minimize failure probability of coastal defence structures, a probability of failure, albeit small, remains. To assist local authorities and the population in...

The effect of short wave breaking on low frequency waves is investigated using two breaker formulations implemented in a time-dependent numerical model (XBeach): (1) an advective-deterministic approach (ADA) and (2) the probabilistic breaker formulation of Roelvink (1993). Previous research has shown that the ADA breaker model gives different...

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...

For the design of cost-effective coastal defence a precise estimate is needed of the 1/10 000 per year storm surge. A more precise estimate requires more observations. Therefore, the three greatest storm surges that hit the northern part of the Holland Coast in the 18th century are reconstructed. The reconstructions are based on paintings,...

Rip currents are wave-induced and off-shore directed flows which occur frequently in the surf zone and can pose a serious threat to swimmers. While the behaviour of rip currents has been studied in swell-dominated environments, less is known about their characteristics in wind-sea dominated environments. This study aims to improve the knowledge...

Regular dune safety assessments in the Netherlands are presently based on a 1D model approach, which is insufficiently applicable for more complex coastal areas with structures, tidal channels or spatially strong varying bathymetry. These situations require more advanced methods to assess the safety in dune areas. In this study a 2DH XBeach...

This paper describes the validation of the dune erosion model XBeach with laboratory measurement data of dune erosion in the presence of sea walls and revetments. Simulation results show that the essential dune set back processes are captured by the model and that the measurements at most locations are approximated quite well. Some aspects...

Extreme coastal storms have a destructive impact on coastal areas and directly affect people living in the coastal zone, being this emphasized by recent events (e.g. Katrina, Xynthia) which reminded the world of the vulnerability of coastal areas. The economic constraints and the increasing vulnerability of coastal areas (due to sea level rise...

A 3 week field study was conducted to investigate the dynamics of low-frequency (infragravity) wave motions over a fringing reef at Ningaloo Reef, Western Australia. Short-period wave motions (0.04–0.2 Hz) were observed to dissipate on the reef crest beyond which infragravity wave motions (0.004–0.04 Hz) gradually dominated toward the lagoon....

Low frequency wave resonance has been postulated to enhance damage to coral reef protected coastlines during storm events. This paper uses the numerical model XBeach to examine the dynamics that contribute to resonance that have been previously observed on a fringing reef on Guam during tropical storm Man-Yi (Péquignet et al., 2009). The methods...

This paper describes the development of a physics-based rip current prediction system called CoSMoS. This system consists of a hydrodynamic prediction system which is composed of a train of surge and wave models from the global scale to the scale of a beach resort (order kilometers). For the beach resort scale model, it is of utmost importance...
