摘要
海滩平衡剖面是海岸近岸过程研究的一个重要概念,在海岸工程中有应用价值。通过分析认为粤东后江湾的海滩剖面处于动态平衡状态。应用Dean、Bodge和Lee等3种海滩平衡剖面模型对后江湾的海滩剖面数据进行拟合,并从地形动力学的角度对拟合结果进行了分析解释,结果表明3个模型中的参数分别包含有波浪周期或波长、剖面变化渐近深度、海滩反射性等物理意义。这可为海岸工程设计确定近岸水下地形轮廓提供重要的依据。
Equilibrium beach profile is an important concept in the coastal proceeding research,which is helpful in the coastal engineering. The beach profiles of Houjiang Bay are dynamic equilibrium. The beach profiles data sampled from the bay are fitted with Dean, Bodge and Lee＇ s equilibrium profile models and morphodynamic interpretion are given subsequently. The results show that the parameters of the models embody information about wave periods or wave length, beach profiles asymptotic depth, beach reflection and the like. The results will be helpful for determining the nearshore zone shape in coastal engineering design.
