Open WL Archief (OWA)

The COB will be 30 m long, 30 m wide and will have a variable water depth of up to 1.4 m. A central pit will allow experiments e.g. with mooring lines at a depth in excess of 4 m. The basin will have state-of-the-art generating and absorbing wavemakers and submerged bidirectional propellers that will drive the recirculation current (velocities of up to 0.4 m/s) across the underground current tank. It will be possible to generate wave-current interactions in the same, opposite and oblique directions. The design of the current generation system has been achieved using both numerical and experimental models. Flow velocity fluctuations are expected to be smaller than 10% RMS. For wind generation, a portable device capable of generating speeds up to 15 m/s is foreseen. The basin will be equipped with state-of-the-art instruments for wave, current, wind and topographic measurements.
