摘要: 本文对长江口水动力与形态过程的最新研究及其在河海大学的应用情况进行了概述。基于声学多普勒海流剖面(ADCP)的测量结果发现了长江口的纵向、横向和水平流循环。通过长期的测量数据对长江口分流点的水动力学机制、水流模式和泥沙通量的变化进行了分析研究。通过现场调查探测出海水从北支向南支入侵。水流运动、泥沙运输和海水入侵的不同数值模型的发展可用于模拟复杂的过程和评估其对工程项目的影响。通过已经建立的数据库对湿地几十年的形态过程进行了分析,并提出了对长江口生态地貌形态模型系统和长期演化机制进行进一步研究的理念。

Abstract: This paper presents a review of the state-of-the-art research and its applications developed at Hohai University relating to the hydrodynamic and morphological processes in the Yangtze Estuary. Longitudinal, lateral, and horizontal flow circulations have been revealed based on the measurements with acoustic Doppler current profilers (ADCP). The hydrodynamic mechanism at diversion points as well as the changing patterns of flow and sediment flux in the Yangtze Estuary has been investigated through long-term data analysis. A field survey has been carried out to detect the saltwater intrusion from the North Branch to South Branch. Different numerical models of flow motion, sediment transport, and saltwater intrusion have been developed to simulate the complicated processes and to evaluate the effects of engineering projects. The morphological processes of wetlands over a time scale of decades have been analyzed with an established database. Ideas for further research on the bio-geomorphological model system and long-term evolution mechanisms are put forward.
