Hydraulic properties that affect the movement of artificial reef blocks caused by waves were examined. Experiments were conducted in a large 30-m-long tank in which artificial reef blocks were moved by waves. Wave height, period, maximum time-filtered velocity, and turbulence were selected as indexes of hydraulic properties that are assumed to influence the movement distance of blocks. Filtering time of the flow velocity that is effective for estimating movement distance was also investigated. Various patterns were also considered for the filtering time of the flow velocity. As a result, the estimation equation for block movement using the maximum value of the 0.1s filtered velocity and the magnitude of its turbulence as an index has the smallest error, indicating that it is important to consider flow conditions, including turbulence in estimating block movement.
