Title

EFFECT OF SUBMERGED VANE SHAPE ON BED SEDIMENT MANAGEMENT

Pages

  37-50

Abstract

 The shape of a SUBMERGED VANE is a major factor in the design of a vane system and affects the performance and SECONDARY CURRENTs generated by the vanes. This study investigated the effect of five vane shapes on bed sediment processes (LOCAL SCOUR at the leading edge and transverse distribution of sediment downstream of the vanes) at four flow intensities for a total of 20 experiments. The results of the comparison of vaneinduced bed-level changes show that a vane with a rounded leading edge and decreased thickness in the longitudinal direction performed best at decreasing LOCAL SCOUR at the edge of the vane by about 17.3% for U/Uc=0.78, 12.3% for U/Uc=0.93, 6.1% for U/Uc=1.10, and 45.8% for U/Uc=1.19. It was found that decreasing the cross-section area of the vane using shape modification decreased sedimentation and increased the sediment bed level on the high-pressure side of the vane.
