As a result of designing an energy absorber in the zone of conjugation of water outlet structures of low-pressure and mediumpressure reservoirs, the stilling basin is not only under the influence of vertical hydrodynamic pressure with a variable value but also the disappearance of stagnation of the stilling basin can also be affected by the hydrodynamic stress arising from the force of horizontal pressure in the energy absorber. The hydraulic jump in the pool junction zone is one of the simplest energy absorbers. To increase the efficiency of this process, it is necessary to improve the hydraulic regime downstream of the water outlet, reshape the interface mode in the stilling basin and on the apron surface, and eliminate flow disturbance, through the construction of special energy absorbers in the stilling basin. These structures exert reactive (accelerating implementation), dislocation (accommodating), and distributed forces on the flow.
