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...master thesis 2009

Boshek, M.R. (author)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,...master thesis 2009

Narayan, S. (author)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...master thesis 2009

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...master thesis 2009

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...master thesis 2009
