• Hydrodynamic characteristics of suspended C shaped bars are investigated.
• Regular waves with wide ranges of wave heights and periods are used.
• Influence of different incident wave and structure parameters is investigated.
• The proposed breakwater type gives efficiency near other similar systems.
The wave transmission, reflection, and energy dissipation of the double rows of vertical piles suspending horizontal steel C shaped bars are experimentally and theoretically studied under normal regular waves. Different wave and structural parameters are investigated e.g. the wave length, the C shaped bars draft and spacing, the supporting piles diameter and spacing, and the space between the double rows. Also, the theoretical model based on an eigenfunction expansion method is developed to study the hydrodynamic breakwater performance. In order to examine the validity of the theoretical model, the theoretical results are compared with the experimental and theoretical results obtained by different authors. Comparison between experiments and predictions showed that theoretical model provides a good estimate to the different hydrodynamic coefficients when the friction factors of the upper and the lower parts are fU = 1.5 and fL = 0.75. The present breakwater physical model gives efficiency near other similar systems of different shapes.
