西南岔河流域产流不均匀系数实例分析

在洪水预报工作中,产流计算是一项重要的分析计算工作,而流域的产流不均匀系数又是影响产流计算的一个关键指标,直接影响产流量的大小和快慢,但流域的产流不均匀系数是一个比较难以实测的参数。文章以西南岔河南岔站为例,对该流域的各项参数进行实例计算分析,求取该区域的经验参数范围,为流域洪水预报基础工作提供参考。

In flood forecasting, runoff generation calculation is an important analysis and calculation work, and the non-uniformity coefficient of runoff production in the basin is a key index affecting the calculation of runoff production, which directly affects the size and speed of runoff production, but the non-uniformity coefficient of runoff yield in the basin is a parameter which is difficult to measure. Taking Nancha Branch Station along Southwestern Cha River as an example, this paper calculates and analyzes the parameters of the basin, and calculates the range of empirical parameters in this area, so as to provide reference for the flood forecasting in the basin.
