Investigation on the Wave Attenuation and Reflection Induced by a Submerged Barrier in Presence of Small Forward and Reversed Currents

Abstract

This paper investigates the wave attenuation and reflection induced by a submerged barrier in presence of small forward and reversed currents using hydraulic model tests, to understand the analysis and prediction of wave reflection, transmission and loss coefficient under the influence of the existing currents with different directions. The wave attenuation and reflection induced by a submerged barrier in presence of small forward and reversed currents is experimentally discussed by using both the regular and irregular wave. Wave attenuation of the embankments affected by external current are also discussed and compared with those of cases without current. The results indicated that the influence of present current on wave reflection is slightly larger for irregular waves than that of regular waves.
