Preliminary research on river channel evolution and comprehensive regulation of the upper reach of the Jingjiang River after completion of TGP

After completion of TGP,the Jingjiang river channel bear the brunt of scouring of clear water discharging from TGP,so the river regime change of Shashi river bend and Haoxue bend in this reach are relatively obvious.With the economy and society development along the river,the comprehensive regulation and development of the upper reach of the Jingjiang River become important increasingly.This paper covers a systematic analysis on the river channel evolution of the upper reach of the Jingjiang River since 1998 as well as after TGP's completion,and a discussion on the task and idea for comprehensive regulation of the reach with a focus on Shashi river bend.
