Abstract
Acoustic Doppler Current Profiler makes it possible to measure current velocity and current direc-tion at any water depth, however, only the data consistent with the traditional six-point method are utilized, and oth-ers are abandoned and wasted. In this paper, based on the theorem to compute vertically-averaged current velocity and current direction by traditional six-point method, formulae were given to calculate vertically-averaged current velocity and current direction by multi-point method. According to in-situ data from Yangshan Harbor sea area and Zhaoyuan sea area, the computation results of vertically-averaged current velocity and current direction by tradition-al six-point method and multi-point method were analytically compared. The results show that the computed vertical-ly-averaged current velocities by two methods are basically identical to each other, however, the difference of cur-rent direction tends to increase when the velocity decreases.关键词
