In revising the river erosion control technical standards survey in June 2012, observation using aDcp (acoustic Doppler current profilers) as one of the methods of flow observation work is published as one of the standard methods. It is well known that the observation results differ depending on the observation environment and observation conditions such as the difference in the structure of the boat mooring aDcp. In this study, we investigated the relationship between the flow velocity data and the rocking behavior of the mooring boat in three mooring boats: Riverboat, High Speed Riverboat, and 3m Riverboat. As a result, in the analysis of the observation results of aDcp in the future, it was considered that it is necessary to compare the relative frequency distribution of the flow velocity value and the rocking of the mooring boat, not to analyze by only the simple flow velocity value. In addition, clarifying the structural condition of the boat by these to be possible to assess the uncertainty of aDcp.
