In the Meiyu period form June 20 to July 12 in 2003, a wide, intensive and lasting rainstorm occurred in the Huaihe River Basin as the complex result of synoptic system, caused a flood with a high water level in the main stream of the Huaihe River and its tributaries at the same time. The main stream of Huaihe River was over its the warning level, the highest water levels for the middle reaches form Zhengyangguan to Huainan were higher than that in history and created the recorded ones. The maximal discharges in the reaches of downstream from wangjiaba were more than those in 1991.
This paper analyzed on the characteristics of the weather, the synoptic causation about the heavy rain, and the condition of incident precipitation and subsequent discharge. The paper expatiated upon the conditions of the flood of 2003 by using the achievement of the restoring computation of runoff of the flood, comparing with the conditions of the historic flood (for example the flood of 1954 and 1991) in Huaihe River Basin. The result indicated that the maximal water quantity in moving 30 days and 60 days at main stations of the stream of the Huaihe River was about once per 10 - 30 years (i.e. the return period is 10~30 years ) respectively. It concluded that the flood of 2003 in Huaihe River Basin was the second largest since 1949 and it was less heavy than that in 1954.
