Study on flood evolution law of Songhuajiang River Main Stream
By analyzing the flood characteristics of Songhuajiang River basin,this paper selects typical floods to simulate the flood evolution process of Songhua River main stream and its tributaries,studies the flood propagation time,peak cutting rate and the superposition law of the flood of Songhua River main stream,and analyzes the relationship between the flood in the upper reaches of Songhua River and the flood in Harbin section.It provides technical support for flood control and disaster reduction in Songliao Basin and flood control safety in Harbin.
