Sediment control is a quantifiable parameter for soil and water conservation engineering.Sabo Dam, for example, not only prevents stream bed erosion but also saves sediment. In this way, the dam can stabilize a fundamental part of the slope. Finally, it can also stabilize the overall slope. However, in the past, when calculating of sediment control, most engineers have only calculated sediment storage volume. The calculation of slope sediment yield reduction volume has been less common. Therefore, this study establishes a method for calculating the stability of slope effect for soil and water conservation engineering. We then calculate the sediment control of the Sabo Dam and bank revetment under three kinds of soil and water conservation engineering. In addition, this study also measured at the actual items to be calculated. Moreover, this work proposes a simple sediment
control calculation method according to the calculated results.
Key Words : Sediment control, Sabo Dam, stabilized slope, bank revetment.
