Study on Application of ADCP in Hydrology of Navigation Safety and Estuary Regulation

Abstract

ADCP (Acoustic Doppler Current Profile) is a new type of current surveying sonar device and is used by acoustic wave Doppler Effect in the early 1980s, and it can measure the speed of relative underwater and the velocity of relative flow. ADCP has been applied widely in flow measurement of the field of marine and inland river and water transport engineering, for example: navigation safety and estuary regulation,etc.. Mainly discussion of theory of ADCP and its application on navigation safety and estuary regulation in the paper. In the future the ADCP is one of the four kinds of advanced marine observation of speed measuring instrument, will be multifunctional, intelligent, lightweight, for development of modern IT and , and applied in scientific research and engineering.
