摘要: 讨论了河网概化的一般原则,并在分析单一河段水流数学模型的基础上,建立了可以适用于一般河网体系水流数值计算的数学模型,并采用荆江—洞庭湖的相关资料进行了验证.结果表明,模型的计算值与实测值吻合较好,说明该模型具有较好的适用性.

Abstract: In this paper a normal principle of the river system is introduced.Based on the analysis of water-sediment model of single reach,a numerical model for calculation of normal river system is established and tested with the observed data of the Jingjiang River and the Dongting Lake. The result shows that the computed data and the observed data fits well,which indicates that it is suitable to describe the complex boundary of the Jingjiang-Dongting,and the model is applicable.
