DISSIPATION BEAMS at the physical model in laboratory

DISSIPATION BEAMS during operation at the model

Upper spillway operate unstable (without DISSIPATION BEAMS)
Lower two spillways operate stable (with DISSIPATION BEAMS)

DISSIPATION BEAMS at the prototipe

Unstable operation of stilling basin: hydraulic jump is pushed off of the stilling basin:

Stable operation of stilling basin: the position of the jump is inside the stilling basin and improve the energy dissipation:
