Wave simulation performance and its quality are key factors to reflect the overall capacity and level of
an ocean engineering basin. They include wave simulating and absorbing capacity of reflected waves. In order to
reduce the influence of reflected waves, various wave absorbing devices are equipped in ocean engineering basins
across the world. The experimental investigation into the performance of combined cambered-type wave absorbing
beach (CCTWAB) with damping bars equipped in Deepwater Offshore Basin is conducted. The experiment adopts
the two-point method. The reflection coefficients are calculated by the method, in which the incident and reflected
waves can be separated from the physically simulated composite waves with different periods and wave heights
in the time domain. The experimental results indicate that in the range of normal wave heights and periods for
model tests, the CCTWAB with damping bars is excellent in eliminating the reflected waves.
