... of VIM and simultaneous wave incidence. VIM model tests with regular and irregular waves collinear to the current conditions were carried out to achieve the goals. The results showed that the waves influenced the phenomenon, although the nature of the wave (regular or irregular) was not the source...

A three dimensional mathematical model is described to analyse the hydrodynamics of the system based on thin-plate approximation and the study is performed within the framework of linear potential flow theory with oblique wave incidence. Results show that a breakwater is in fact capable of reproducing...

Three angle of incidences for each model were tested, namely 0, 22.5 and 45 degrees related to the current incidence. Different VIM response was observed due to the column design. The maximum amplitude...
