Popis:	Deterioration of water quality becomes severe problems in some harbors because the circulation of water in the enclosed region by breakwaters is weakened and exchange of water becomes inactive there. Submerged breakwaters and floating breakwaters have an advantage over the impermeable breakwaters in that they can more easily exchange water. However, they are not effective to maintain harbor tranquility. We have already shown that breakwaters with slope-type channel and step-type channel effectively reduce transmitted wave height when compared with a straight-type channel.In this study, the flow rate through the breakwater with channel is examined by experiments and numerical model to investigate the effect of channel in tidal current. It is found that the flow rate can be estimated from the non-linear Darcy's law where the difference between the water surface levels in and outside of the harbor plays an important role.
