黄河口以水少沙多、流路多变、不断淤积大量新生土地(湿地)而著称于世。本文根据实测资料分析、理论探讨、数学模型计算等方法,对黄河口水沙运动与演变基本规律进行了系统的研究,主要内容包括:河口潮汐特性、潮流特性,海洋动力的输沙能力,河口泥沙的输移与扩散,河口的淤积延伸、蚀退与造陆,河口拦门沙的形成过程与演变特性,河口流路演变及对下游河道的反馈影响,河口异重流的形成与发展,河口三角洲湿地的发展等。通过与世界其它主要河口的比较,进一步加深了对黄河口———这个独具特色的河口的认识。研究成果为黄河口的综合治理提供了科学的依据。
The Yellow River estuary with less water and more flow channels change, constantly silting a large number of newborn land (wetlands) and is known to the world. Based on the analysis of measured data, theoretical analysis and calculation of mathematical model, this paper systematically studies the basic rules of water and sediment movement in the Yellow River Estuary. The main contents include: tidal characteristics of the estuary, tidal current characteristics, sediment transport capacity of marine power, The transport and diffusion of sand, the deposition and extension of estuaries, the ebb and flow of land, the process of formation and evolution of estuarine barren sand, the evolution of estuarine channel and its feedback to downstream rivers, the formation and development of heavy streams in estuaries, Estuary delta wetland development and so on. The comparison with the other major estuaries in the world has further deepened our understanding of the Yellow River Estuary, a unique estuary. The research results provide a scientific basis for the comprehensive management of the Yellow River Mouth.
