Analysis on the river evolution of Zhenyang reach in the Yangtze River based on GIS

WANG Xiang-dong~1,TANG Li-qun~1,DING Xian-rong~2(1.China Institute of Water Resources and Hydropower Research,Beijing 100044;2.Hohai University,Nanjing 210098)  
The GIS for Zhenyang reach in the Yangtze River is developed which includes automatic mapping system,terrain information management system and deposition-scouring analysis system.The spatial technique of GIS is applied into the analysis system of deposition-scouring.The deposition-scouring analysis for any time interval and any location or area has been realized in this study.The analysis system shows many advantages in river management,such as auto-mapping of river terrain,spatio-temporal management of terrain information,3D terrain expression etc.The deposition-scouring analysis system will supply scientific data for river planning,management and regulation efficiently.According to the digital terrain information,the river evolution processes of zhenyang reach in the Yangtze River are analyzed finally.
