Study on the impacts of floating seaweed on wind waves

As human beings are becoming more and more aware of importance of the environment, resorts to clean energy have provoked great interest for the past decades. As a sort of clean power, wind has been widely considered as an ideal energy source to generate electricity. That is why the offshore wind farm plans have been drawn up, specifically in...

Drag forces on vegetation due to waves and currents

Vegetation in coastal areas plays an important role in its environment. In addition, vegetation can also be utilized for coastal protection. Incoming wave energy could be effectively attenuated by the upstanding vegetation plants. The reduced wave energy results in stabilized seabed and harmonious environment in coastal zones. Nowadays, an...

Stevin Outlet Sluices: Wave impact under a beam

The Dutch department of Public Works had a problem regarding wave impacts on a beam in the Stevin outlet sluices, located in the Afsluitdijk. Wave impacts on this beam could also cause a peak pressure on the barrier gate, just behind the beam. The numerical program ComFLOW and physical scale experiments were used to predict the wave impacts for...

Study of fatigue design on marine current turbine support structure Bali - Indonesia

Clean Green energy is being desired all over the globe. It gives cleaner world and healthier environment to live. Most of the green energy resources such as tidal and wave are freely available in large amount and also sustainable. On the other hand, the energy demand is increasing along with population growth. Therefore, researchers are...

Spatial distribution of wave overtopping

The goal of this master thesis is to describe the spatial distribution of the wave overtopping discharge over and behind the crest of a coastal defence structure. The influence of the most relevant parameters on this process is explored. This research has been performed by means of a physical model. The following relevant parameters were varied...

Generating electricity from waves at a breakwater in a moderate wave climate

The purpose of this thesis was to develop a preliminary concept design of a wave energy converter. The type of device designed was limited by several starting points which stipulated, among other criteria, a robust structure which can be constructed within a breakwater and can generate electricity from a fairly mild (in the order of Hs=0.5-1.5m)...

Golfreflectie bij golfbrekers

Een teenconstructie van een golfbreker is het deel van een golfbreker dat zich aan de onderzijde van het golfbrekertalud bevindt. Een teenconstructie geeft steun aan het voortalud van de golfbreker en voorkomt, samen met andere golfbrekeronderdelen, het wegspoelen van constructiemateriaal en ondergrond vanonder een golfbreker. Bij het...

Validation of the numerical wave models SWAN and HISWA at Norderney

In coastal engineering waves often play a dominant role. To predict the wave behaviour in coastal regions numerical wave propagation models have been developed. This study deals with the verification of two models against measurements in the field, namely HISWA and SWAN. The second generation model HISWA has already proven to perform well for...
