概念性河口及长江口淤积机制分析模拟
Simulation of deposition mechanisms in the Yangtze River and conceptual estuaries
摘要
Abstract
To identify the reasons for deposition in estuaries, we first establish a two-dimensional mathematical model of flow and suspended sediment transport in the Yangtze River and conceptual estuaries by generalizing estuarine mor-phology; next, we simulate and analyze five types of deposition mechanism in the conceptual estuaries; then, we simulate the hydrodynamic characteristics of the flow and sediments and discuss reasons for deposition in the Yangtze River Es-tuary. It can be safely concluded that the establishment of the model of conceptual estuaries contributed to the under-standing of the deposition mechanism in different estuaries. In the Yangtze River Estuary, the deposition mechanisms in different reaches vary; therefore, appropriate measures should be taken during any engineering work. This research can help the efficient use of estuaries as a resource for society.关键词
