摘要:

分三个方面介绍了河口最大浑浊带研究中数学模拟研究的进展:(1)利用通量分析计算河口盐度、污染物和泥沙通量,分析带内泥沙富采机制;(2)由物质平衡原理建立一维和较简单的机理模型,讨论最大浑浊带的成因;(3)据水动力方程和物质平街方程建立二维或三维数值模型,计算最大浑浊带的水流结构和物质浓度分布,模拟并探讨不同条件下最大浑浊带的成因和演化机制。

关键词: 河口最大浑浊带数学模型    
Abstract:

In this paper, the advances of mathematical modeling of turbidity maximum in estuaries are introduced in three aspects:① To calculate salinity,contaminant and sediment concentration with flux analysis method to study the mechanism of sediment amassing in estucries.② To establish one dimensional model or some simple model with mass balancing principle to explain the formation of turbidity maximum.③To establish two or three dimensional numerical model with momentum and continuous equations to calculate the dynamical feature and the distribution of mass concentration in estuary. Then analyse the formation and development laws of turbidity maximum under various assumptions.

Key words: Turbidity maximum    Mathematical modeling.
