摘    要:基于波浪掀沙和流输沙的物理图形,本文根据能量平衡方法和扩散理论分别推导得出了破波区内外含沙量的横向分布表达式,研究结果表明,破波区内趋近岸线的含沙量并不为零,与实测资料相吻合,采用泥沙扩散议程计算破滤区外的含沙量的横向分布,弥补了Fick扩散模型不考虑泥沙沉速的不合理性。

关 键 词:黄河河口 含沙量 泥沙沉速 物理图形 横向分布

Abstract:Based on the energy equilibrium principle and diffusion theory, the expressions of transverse distribution of suspension concentration inside and outside of the breaking wave zone are deduced. It is found that the concentration inside of the breaking wave zone near the coastline is not equal to zero, which is in agreement with the measured data. Since the setting velocity is included, these expressions are more reasonable than those deduced from Fick's model, in which the setting velocity is not being considered.
Keywords:breaking wave zone  suspended sediment concentration  sediment setting velocity  particle lifting  sediment transport
