In this study, a series of new laboratory experiments were performed in a wave-current flume in the presence/absence of tidal current. Experimental results are reported for a variety of combined wave-current conditions based on an idealized barrier reef model. Result analysis shows that the mean water level on the reef flat was consistently lower during the shoreward current (flood tide) than that during the seaward current (ebb tide). Maximum wave set-up on the reef flat decreased significantly as the current flowrate changed from its seaward maximum to its shoreward maximum. A theoretical model, which was derived based on the cross-shore balances of momentum and energy, was proposed to reproduce the wave set-up on the reef flat in the presence of current. The model was then validated by the laboratory data. The key model parameter was found to decrease rapidly with increasing current flowrate.

潮汐流作用下在堡礁上的波浪诱导设置

在这项研究中，在存在/不存在潮汐流的情况下，在波浪流水槽中进行了一系列新的实验室实验。报告了基于理想化堡礁模型的各种组合波流条件的实验结果。结果分析表明，在岸流（大潮）期间，礁滩的平均水位始终低于向海流（退潮）期间的平均水位。随着海流流速从向海最大值变为向岸最大值，礁滩上的最大波浪设置显着下降。提出了一种基于动量和能量的跨岸平衡推导出的理论模型，以重现存在水流时礁滩上的波浪设置。然后通过实验室数据验证模型。
