Abstract: Under the framework of the EU-funded project DELOS, 3D tests were performed in the 12.5x9.7 m wave basin at Aalborg University, DK, with the aim of analysing waves and currents around low-crested structures. The paper compares experimental and numerical results on flow circulation patterns in a symmetric layout, composed by two detached breakwaters forming a rip channel in the middle. The 2DH model MIKE 21 is applied to reproduce wave and current flows around the structures for some laboratory tests selected to represent the effects on flow circulation of the following parameters: wave height, spectrum type, wave steepness, berm width. Computed velocities and water levels are checked using the measured data, and computed circulation patterns are compared to those obtained by image analysis of video recordings.
