长江上游中小洪水雨洪特征分析
Analysis of rainfall flood characteristics of small-medium floods in upper Yangtze River
摘要
Abstract
To disclose the formation mechanism of small-medium rainfall flood from the perspective of synoptic meteorology, the two are combined in the analysis. Based on the daily rainfall data of meteorological stations and daily-mean-discharge data of the main control stations on the mainstream and tributaries of the Yangtze River from 1981 to 2012, by consideration of the Three Gorges Reservoir operation, we selected the small-medium floods in the upper Yangtze River by self-defined conditions. The analysis of the distributuion of small-medium flood and rainfall flood characteristics shows that the self-defined conditions are reasonable;the medium and small floods decreased gradually;the floods are in June to September mostly and no flood occurs in level fall period of Three Gorges Reservoir;the areal rainfall of middle and small floods in the six major river basins ( regions) in June increase are from the west to the east.关键词
