Abstract:
The major flooding event during the summer of 2007 in Huaihe River Basins is stu died based on the observed data of precipitation and hydrology. The analysis of the spatialtemporal distribution of precipitation during the flooding period a s well as the hydroclimatology features is also carried out and compared with historical data. As shown from the results, the heavy rainfall occurred during t he period from 29th June to 26th July with four stages linked to four flood peak s of Huaihe River. Higher precipitation is correlated to more flood water flow, then leading to higher waterlevel. The persistent and heavy rainfall in the up per and middle Huaihe River brought about the major flood in 2007, although the average amount of precipitation for Huaihe River Basins during the flooding peri od of 2007 was equivalent to 2003.
