摘要: 利用所构建的非恒定输沙数学模型,对黄河下游铁谢至孙口河段内的1977年高含沙洪水、1982年大水少沙型洪水以及1996年典型洪水进行了数值模拟.模拟结果证明了数学模型的可靠性,表明该模型不仅能模拟黄河下游河道一般洪水和高含沙洪水的水沙传播、水位变化及河床变形等,而且对模拟现行严重萎缩河道内的洪水演进及河床冲淤特性也有较好的适应性.

Abstract: The three typical floods occurring in 1977,1982,1996 in the lower Yellow River from Tiexie to Shunkou with a length of 393.67 km are numerically simulated by the established mathematical model for unsteady sediment transport.The computed results,such as the discharge,water stage,sediment concentra tion,cross sectional erosion and deposition,agree well with the observed data and validate therefore the mathemat ical model.
