Songhuajiang River In Jiamusi To Tong Jiang Fujin - Shallow Riverbed Evolution Suidong Analysis

The research range of this article is the key shoals in Fujin shoal (620km~635km)and Suidong shoal (635km~643km)River in the Songhua River Jia-Tong linereach.Based on the field investigation, fieldsurvey,hydrologic analysis,through theresearch of depth plan in1972,depth plan Jia-Tong line phase in1996after theregulation project, depth plan in2001and riverbed topographic map in2010, the sectionof the river bed level changes,changes in vertical as well as horizontal changes made tothe research. Through the study on shallow riverbed evolution analysis on the lowerreaches of the Songhua River from Fujin city to Suidong city,studying the evolution lawof river course, the future development trend and shoals characteristics. As the shipnavigation safety guarantee and investigation work provide a theoretical reference.
