Title

Experimental Study of Combined Flow Trapezoidal Labyrinth Weir-Gate with One Cycle

Pages

  62-74

Abstract

 The combined weir-gate is important hydraulic structure in management of irrigation canals. On the other hand, the use of labyrinth weirs can reduce water level fluctuations due to longer crest lengths than linear weirs for a specific discharge. Because of the sediments deposition in upstream of the weirs the flow conditions change and the accuracy of the presented relationship is reduced. Therefore, the use of combined flow trapezoidal Labyrinth weir-gate can be a useful solution for passage of floating substances over the weir and sediment transport under the gate. In this research, experimental study of combined flow trapezoidal Labyrinth weir-gate with one cycle has done for three Sidewall angles of 15, 20 and 25 degrees, three gate openings 2, 4 and 6 cm and three weir heights of 14, 17 and 20 cm in a rectangular channel. Based on the effective parameters of the combined models, the mean Discharge coefficient has obtained in the range of 0. 61-0. 75. The results show that the Discharge coefficient decreases with increasing the ratio of Ht/P, and it reaches a constant Discharge coefficient of 0. 61 for Ht/P >0. 6. The Discharge coefficient of the combined model increases by increasing the angle of weir. Also the results show that the Discharge coefficient of trapezoidal Labyrinth weir-gate has the highest value for weirs with a Sidewall angle of 25 °,and gate opening of 2 cm.
