| 摘 要： | 在概化基本单位为V形基本单元和马蹄形基本单元基础上,提出了分布式汇流模型(即坡面汇流、河道汇流模型).给出了坡面汇流V形、马蹄形基本单元面积-时间曲线及时段单位线方程,推求了基本单元坡面最大汇流时间;利用马斯京根法建立了河道汇流的水量平衡方程和槽蓄方程.以沿渡河流域为例,概化出59个基本单元,计算出内、外单元的平均面积、链长及坡长,采用新安江模型分析沿渡河流域的雨洪资料,利用其中10场地表径流资料对模型参数进行率定,验证结果表明模型合理可靠,具有较好的实用价值.

| Abstract: | Based on generalizing basic cells of V-shaped cell and U-shaped cell,this paper advanced a new distributed hydrological conflux model.In this paper,area-time curves,period of time UH equations and the longest conflux times of V-shaped cell and U-shaped cell,which were useful in slope conflux computation,are deduced.Rivertree conflux computation adopted Muskingum method to simulate.Taken Yanduhe watershed,for example,59 basic cells are generalized,the average areas,chain lengths and slop lengths of inside ce... |
