Analysis SWAN hindcasts Wadden Sea, Oosterschelde and Slotermeer

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...

Improvement of the numerical efficiency of SWAN: SBW Waddenzee

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...

Evaluation of a multigrid method for the reduction of the computational time of SWAN

The spectral wind wave model SWAN 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 SWAN for application to the geographically complex area of the Wadden Sea, a number of activities have been initiated...

Onderzoek onzekerheid extreme golfbelastingen: Effect stromingen op golven Stappenplan toepassing SWAN model

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...

Guide for the program Exact-NL

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...

Computation of the nonlinear energy transfer in a narrow gravity wave spectrum with a method derived by Dungey and Hui

In this report the method of Dungey and Hui is summarized and extended to include the effect of skewness of the directional distribution. Additional information is given about the derivation and computation of the single integrations mentioned above. The method of Dungey and Hui is applied to a number of theoretical spectra. The results of these...
