Experimental Study on Interaction among Waves, Currents and Bottom Topography

The experimental results of the interaction among wave, current and a submerged mound have been reported in this paper. This study is carried out for the cases where the wave is propagating in the following and the opposite direction of the current over a submerged mound of parabolic cross section. The phenomenon is investigated for varying forced currents, mound geometry and relative water depths. It is found that following current amplify the wave height over the mound but reverse current over the whole domain. Other results indicate that current of both directions affect the wave characteristics significantly over the mound.
