中文摘要：
为了探求河口淤积原因,从概念河口的角度出发,通过概化河口形态建立概念性河口模型,以二维水沙数学模型为工具,模拟分析了5种河口淤积机制;建立了长江口水沙二维数学模型,对长江口区域水沙特征及淤积状况进行了模拟分析。研究表明,建立概念性河口有助于研究不同形式河口的淤积机制,对于长江口水域,其不同区域淤积机制不一,其治理措施也应有所区别,找出河口不同区域起主导作用的泥沙淤积机制,有利于人们更合理地治理河口。
英文摘要：
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.
