Komani HW relief system with

• Exposure structures with jump
• Endbereich der Entlastungstunnel
• Energy conversion in the adjacent water section

The focus of the 1:72.7 scale model tests was on the hydraulics of the outlet structures, their positioning, and the reservoir sections near the outlets or the impact area of the impinging jets.
