Abstract
In this study, the analysis results were presented for the experimental data of sluice for tidal power generation that were installed in an open channel flume. The experiment was carried out for the six different sluice models of different widths and bottom heights of the sluice throat section. If the side shape of the sluice was the same, the coefficient of discharge generally increased by increasing the width of the throat section. However, when the water discharge was small and the upstream water level was low, the coefficient of discharge increased for a while but decreased later with the increase of the throat section width. In addition, the coefficient of discharge was larger when the bottom height of the throat section was higher, regardless of the width of the throat section. It was concluded that the values of coefficient of discharge that were frequently used in the previous feasibility studies were underestimated so that should be adjusted to higher values.
