Preliminary research on annual flood period division of Taihu Lake
摘要
Abstract
A preliminary study for the flood period division of Taihu Lake can increase the water resources utilization efficien-cy. Firstly, according to the empirical statistics and by using the observed data of inflow from 1986 to 2010, distribution graphs of the maximum 1d average flow in 10 days and 3d average flow in a month are drawn respectively, and on this basis, we can ob-tain the occurring times of peak flood flow in a period of 10d, and approximately determine a division of five flood periods. Then, the fractal theory is applied to compute the capacity dimension for the serial samples of maximum daily flow of Taihu Lake in a whole year, and also a division of five flood periods is determined. The calculation by fractal theory not only can get the same re-sult as the empirical statistics, but also has the quantitative and objective characteristics, providing a basis for the annual flood period division of Taihu Lake.关键词
