摘要
在分析寒区河流封冻期与畅流期两种退水曲线的基础上,采用差积法来近似估算河网冻结水量,改进了冰厚调查测量和采用融冻期流量过程分割的常规方法。经退水过程概化后,计算得到了简化,并以科后站为例,计算了部分年冻结水量,该方法计算结果较为切合实际。
On the basis of analyzing two kinds of the ebb curve during sealing the river passes and flowing freely in the severe area,this paper adoptes difference accumulation method to estimate freezing water quantity and to improve ice thinkness investigation and to adopte practice method of flowing process segmentation during melting.After the ebb process is goneralized,the calculation is simplified,and taking Kehou Station as an example,it calculates some freezing water quantity.The method corresponds practice after compare.
