摘要
根据山溪性河流特点 ,提出了符合实际的断面概化方法 .考虑河流与地下水的交换作用 ,将渗流量作为联接条件 ,利用迭代法解决了河道水流与地下水流模型的耦合 .计算实例表明 ,模型设计是合理的 .
Based on the characteristics of mountainous rivers, a practicable method for cross section generalization is proposed, then a coupling model is developed for simulation of exchanges between river water and groundwater by use of the iteration method. A case study shows that the present model is reasonable for simulation of unsteady flows of mountainous rivers.
