Janssen, M.P.J. (author)
Although mangrove forests have proven to contribute to wave dissipation significantly, these ecosystem are threatened mainly by the expanding aquaculture. International or nationwide applied greenbelt policies are often used for the preservation of the mangroves and hence the flood hazard reduction, without taking local (hydrodynamic) conditions...

Since their development in the 1970s, mesoscale atmospheric models have been used for a variety of meteorological applications. Over the years, the models have evolved and nowadays, state-of-the-art atmospheric models are capable of operating on spatial resolutions in the order of kilometres. In the hydraulic engineering community, atmospheric...

The objective of this study is to determine whether a floating terminal could be a suitable and feasible solution for the realisation of a new berthing location for the cruise ships of the future. This feasibility study is based on the amount of downtime of a terminal due to excessive motions because of wave loading. Therefore, this study...

On the south-west coast of Namibia, diamonds were trapped during the Quaternary on bedrock platforms and in bedrock gullies. These were formed by differential erosion due to wave action. The diamonds originated from Kimberlite diamond pipes within the catchment area of the Orange River in South-Africa and Botswana. This river eroded the diamonds...

Durban is located on the east coast of South Africa in the province of KwaZulu-Natal. It is one of South Africa’s biggest cities and has one of the busiest ports in Africa. To maintain Durban’s current economic position the Durban Port has to expand, which is problematic due to a lack of space. A solution is to develop a completely new port: the...

The Dutch Flood Defense Act prescribes the assessment of the safety level of Dutch primary sea and flood defenses every six years. To asses if the required level of security of the sea and flood defenses is guaranteed, first the Hydraulic Boundary Conditions (HBC) which the sea and flood defenses are exposed to, have to be determined. At the...

Recently an unstructured version of Delft3D, named D-Flow FM, has been developed at Deltares. This tool shows high potentials for coastal modelling due to the flexibility in domain resolution and unstructured grids. This MSc thesis focussed on implementing wave effects in D-Flow FM with satisfying results. In addition, a coupling system is built...

Volgens de Waterwet dienen elke zes jaar de Hydraulische Randvoorwaarden (HR) te worden vastgesteld. De HR bestaan uit hoogwaterstanden en golfrandvoorwaarden voor de toetsing van waterkeringen gegeven overschrijdingskansen welke in de wet zijn vastgesteld. Ook voor waterkeringen in havens en afgeschermde gebieden dienen de HR vastgesteld te...

Benit, M.P. (author)
As waves enter the surf-zone, the wave spectra undergo drastic transformations because of depth-induced breaking and triad interactions. Any arbitrary spectrum will converge towards a smooth, universal shape in which initially higher harmonic peaks emerge that disappear as wave propagate further into the surf-zone. The current formulation of...

Diffraction diagrams are frequently utilized by engineers within the feasibility and early design phases of a project. These helpful graphics, based on directional spreading and wavelength, can be used for a number of layouts and angles of incidence. In spite of the tendency to design breakwaters for the fullest dissipation of wave energy,...

A study of the effectiveness of mangroves in attenuating cyclone- induced waves was done using the SWAN 40.55MOD numerical model. Hydraulic parameters during extreme events and local mangrove vegetation parameters were estimated for the Kanika Sands mangrove island near the upcoming Dhamra Port in Orissa, India. Simplified generic analyses were...

Van der Ham, P.J. (author)
Part I: On the time scales of wave processes. To systematically improve the SWAN model a study on the wave physics in a tidal inlet was carried out. The third-generation SWAN model was used to compute the wave processes in a tidal inlet for storm conditions. The computed wave processes are propagation (shoaling, refraction and frequency shifting...

Dusseljee, D.W. (author)
Strong ocean currents such as the Agulhas Current near South-Africa are alleged to generate freak waves due to the enhancement of wave energy under counter-current conditions. It has been suggested that such enhancement is due to current-induced refraction but it is actually the result of a balance between many processes. To understand this...

The discovery of great oil reserves located under the northern part of the Caspian Sea has lead to an increased interest in the wave climate in this area. Statistical analysis of wave measurements is insufficient to determine reliable design wave conditions on the northern part of the Caspian Sea, because the amount of available wave...

Vink, A.S. (author)
One of the most applied models for wave prediction is the spectral wave model SWAN. SWAN is not always capable of predicting wave conditions in the surf zone with sufficient accuracy. In this study the transformation of wave spectra across the surf zone and its spectral modelling was investigated. The objective of this thesis work was to improve...

In the past years the SWAN wave model was developed. SWAN is a third-generation spectral wave model for applications in coastal areas. The verification of the model has been carried out for a few laboratory and field experiments. In this thesis the DELILAH field experiment held at the property of the Field Research Facility in Duck, North...

SWAN is a so called third-generation spectral wave model for applications in coastal areas. The existing model is still subject to further extensions. One of these extensions is a non-stationary option that makes the model suitable for use in large geographical areas. As part of the development of a non-stationary option of the SWAN model, tests...

Voor wie in de offshore werkt vormen golven een bedreiging. Bij de installatie van boorplatforms bijvoorbeeld is het belangrijk een aantal dagen van tevoren te weten wat het golfklimaat en de weersomstandigheden zullen zijn op de plaats en het tijdstip waarop de installatie zal plaatsvinden. Voor aannemers die onderhoudswerk verrichten aan...

Because of recent measurements and the first results of new calculations on the sea dike of Petten, Noord-Holland, the question has risen whether or not the sea dikes along the Dutch coast are high enough. A criterion which indicates whether or not a dike is high enough is the level above NAP which is exceeded by 2 % of the uprunning waves under...

Doorn, N. (author)
Waves that approach the coast and encounter obstacles such as small islands, rocks or breakwaters may be reflected backwards and in lateral directions, but the wave crest may also bend around the obstacle. This phenomenon can be described with refraction-diffraction models based on the Boussinesq equation or the mild-slope equation of Berkhoff....
