摘要
Abstract
The calculation of drainage modulus is important for determining the layout and scale of drainage works. Taking the flooded areas of Baoqing of Raoli River and Muleng River in Sanjiang plain in eastern Heilongjiang Province as an example,based on the row of runoff gen-eration characteristics of underlying surfaces in the drainage area,drainage modulus formula method and average method were used respec-tively to calculate the drainage modulus under different drainage standards and analyze the two kinds of the drainage modulus calculation method. The results show that the drainage and drainage modulus are larger as the recurrence period grows. In the dry field, the difference between the waterlogging modulus is smaller,the smaller the area,the smaller the difference of waterlogging modulus,and the overall results of the average elimination method are larger than the formulae. The difference of waterlogging modulus is relatively large and the smaller the area,the larger the difference.关键词
