can simulate flood discharging conditions and accurately reflect ground vibrations through linear prediction. The vibration energy of the dam orifice was the primary vibration source of ground vibration, followed by the guide wall and stilling pool base slab. Findings from our investigation show that orifice open and upstream and downstream water levels were the major influences on ground vibration intensity, thus controlling these factors and regulating the discharge modes from a high dam will control the intensity of these vibrations.
