| Abstract: | Aimed at the problem of how to get the real-time water level with high density in the tidal propagationlinearly waters,this paper illustrates in detail the needed resources key technologies and mathematical models fortechnical realization.It is introduced through examples how to get the main technical design contents of real-timewater level with high density in Pearl River Estuary channel waters,and the tidal data accuracy is verified.Theresults show that the error is within 7.cm.Finally,we look forward to the application aspect of the real-time waterlevel with high density and acquisition technologies. |
