| 摘 要： | 根据节点水沙平衡和能量衔接条件,在单一河道水沙数学模型的基础上,建立了可以适用于一般河网体系水沙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,说明对荆江-洞庭湖区域复杂边界条件的处理是合适的,所建模型具有较好的适用性。

| Abstract: | According to the requirement of mass and energy continuity of water and sediment and the analysis the water-sediment model of single reach, a numerical model for calculation og the normal river system is established in this article, and tested by the observed data of the the Jingjiang River and the Dongting Lake in 1997. The result shows that the computed data and observed fits well, which indicates that it is suitable to sum the complex boundary of the Jingjiang-Dongting Lake and is applicable. |
