Abstract: In order to ensure the safety of Shanghai Chenhang reservoir during levee operation, professional testing means are used for dynamic monitoring of underwater terrain. Combination of GPS-RTK technology and echo sounder is adopted. As well, overall topographic survey and the fixed cross section measurement are carried out. Measurement results are reasonably processed and visualized, visually displaying the global and local underwater terrain change on the river side, which provides professional data for safe operation of the levee.

Key words: Chenhang reservoir, safety management, underwater topographic survey, dynamic monitoring
