Due to their zigzag geometry in plain view, labyrinth weirs require less crest length compared to linear weirs in the dam body or in the channels where they are placed. In this study, the effect of the number of cycles (N) and weir heights (P) of the semi-circular labyrinth weirs on the flow efficiency was investigated. Semi-circular labyrinth weirs, unlike triangular and trapezoidal labyrinth weirs, increase the discharge efficiency by making the areas that reduce the flow capacity at the intersection areas more efficient and by allowing the flow to move in a more perpendicular direction to the weir walls. The experiments were carried out on 3 different configurations (N=2, 3 and 4) depending on the number of semi-circles they contain. In all configurations, a total of 3 weir heights (P=0.20, 0.30 m and 0.40 m) were used and 9 test setups were prepared. In addition, to reference the results obtained from circular weirs, experiments were carried out with linear weirs at 3 different weir heights (P=0.20, 0.30 m and 0.40 m), and a total of 12 experiments were carried out. n this study, the effect of the number of cycles (N) and weir heights (P) of the semicircular labyrinth weirs on the discharge efficiency was investigated. The results obtained from the circular labyrinth weir experiments were compared with previous studies and it was seen that the semi-circular labyrinth weirs had higher discharge capacity than the triangular labyrinth weirs. In addition, semi-circular labyrinth weirs provided a longer effective crest length than the triangular form with the same channel width, they provide higher flow rates at the same weir load. © 2023, Gumushane University.
