The determination of wave conditions in partly sheltered areas is a challenging task for coastal engineers. Knowledge about these conditions is important for the design of coastal structures, the planning and operation of ports. Numerical models play an important role in the assessment of these conditions. Various types of models have been...

This study presents an intercomparison of a SWAN and SWASH wave model and 3D laboratory experiments for an existing navigation channel towards a harbor. Results show that the spectral refraction model SWAN underestimates the wave conditions in the channel and at the lee side of the channel especially - for longer waves travelling under a small...

This paper presents the application of new source terms in SWAN for the dominant water wave physics in the coastal zone: depth-induced breaking and triad wave-wave interactions. We present results demonstrating increased modelling skill in the prediction of bulk wave parameters e.g. significant wave height and of the spectral shape compared to...

Wave penetration inside harbours has been one the main issues that port planners and engineers have had to deal with in recent years. Wave conditions inside harbours trigger vessel movements, create dynamic loads on port structures and condition harbour exploitation and safety. For this reason in the recent past maritime and port engineers have...

The SWAN model is a third-generation spectral wave prediction model developed by Delft University of Technology. Since its initial release in 1998 this model has become a widely used and reliable tool for offshore and near shore wave predictions. Its main field of application is the coastal zone where, by virtue of its implicit numerical scheme,...

This poster describes the results of some studies performed on the development of an efficient and operational SWAN model for the Black Sea. This model will be used to study the wind-wave climate and wave energy potential in the region and will provide boundary conditions for coastal engineering and nautical activities. The present model...

Characteristics of the individual wave height distribution in shallow water have been investigated using measured wave data and results of numerical simulations using the non-hydrostatic SWASH model. It is shown that the SWASH model is capable of reproducing the temporal and spatial variation of surface elevation in a wave flume and the...

This paper addresses the on-going activities in the development of efficient methods for computing the non-linear four-wave interactions in operational discrete third-generation wind-wave models. It is generally assumed that these interactions play an important role in the evolution of wind generated surface gravity waves. Therefore, present day...

The performance of the spectral wind wave model SWAN in tidal inlet seas was assessed on the basis of extensive wave measurements conducted in the Amelander Zeegat tidal inlet and the Dutch Eastern Wadden Sea, as well as relevant data from other inlets, lakes, estuaries and beaches. We found that the 2006 default SWAN model (version 40.51), the...

Results of hindcast studies with the SWAN wave model in the Amelander Zeegat, the Oosterschelde estuary and the Slotermeer were analyzed to detect the cause of under-prediction of low-frequency wave energy in the coastal zone, the causes of prediction errors in the presence of currents and the underprediction of wave heights In depth-limited...

The spectral wind wave model SWAN (Booij et al. 1999) plays a key role in the estimation of the Hydraulic Boundary Conditions (HBC) for the primary sea defences of the Netherlands. Since some uncertainty remains with respect to the reliability of the wind wave model SWAN for application to the geographically complex area of the Wadden Sea, a...

Modern design formula for coastal structures (like rock stability formula and overtopping formula use wave parameters (H2% and Tm-1,0) which are not readily available from standard boundary condition wave data. For transforming values like Hs and Tp to the parameters used in the new formulas, often-fixed conversion factors are used. However,...

Ten behoeve van het ontwerp van zeewerende constructies van nieuwe landaanwinningswerken van de Maasvlakte 2 is onderzoek verricht naar onzekerheden in de bepaling van golfrandvoorwaarden onder ontwerpcondities. In dit deelrapport is gekeken naar het effect van stromingen op de golfcondities voor de zeewerende constructies. Hierbij is gebruik...

A detailed description is given of a set of programs called EXACT-NL, which computes fetch- or duration limited wave growth with an explicit expression for the resonant four-wave interactions. This guide is meant as a user's manual. lt describes the principles and usage of each program of the EXACT-NL model. We used the EXACT-NL model for the...
