The turbulence-suppressing rubber dam effectively prevents oscillations and creeping phenomena that can damage the dam body's downstream friction-protection layer.
Due to the variable nature of river conditions—including fluctuating flow rates and velocities, as well as overflow discharge and downstream tailwater dynamics —rubber dams are susceptible to either whole-body oscillation or localized vibration. This issue is addressed through the use of turbulence-suppressing baffles. Positioned behind the water curtain flowing over the dam crest, these baffles use pneumatic pressure to equalize forces; they serve as the primary control system for the rubber dam's resistance to oscillation.
