AB - The objectives of this study were to evaluate effects of the flat-board debris-flow breaker (FDB) equipped with side screen and to derive an optimal slit aperture of the side screen for maximizing its positive effects. The results showed that only a few small-sized materials were passed through side screen, causing storage at both sides of FDB. Instead, a massive amount of large-sized materials was trapped on the upper surface of FDB regulated by side screen, and this coarse layer was filled with fine sediment. This fining may not arrow passage of even fine materials from upper to lower surface of FDB. Meanwhile, concerning the damage reduction by debris flows, there was no functional difference between the mean and maximum grain-size slit apertures. However, because a larger slit aperture of the screens has an advantage in reducing construction costs, the slit aperture of FDB should be matched to the maximum grain size of bed materials.
