Year: 2021

Type: conference-paper

Abstract: As an important control station for the mainstream of the lower reaches of the Yangtze River, studing the runoff change characteristics in dry season at Datong Hydrological Stations can provide a comprehensive grasp of the hydrological conditions in the lower reaches of the Yangtze River. This study uses linear trend method, Mann-Kendall method and wavelet analysis method to analyze the dry season runoff change characteristics at Datong Station, and the following conclusions are obtained: the average flow in the dry season at Datong Station has shown a significant increasing trend and a significant change period, while the first main period is 35-year; for the typical dry months, there is no significant increasing trend in December, but the increasing trend is significant in January and February; The dry season runoff at Datong Station accounted for a significant increase in the proportion of the entire year since 2003.
