抄録

Experimental results on flow characteristics around oblique weirs in a compound open channel are presented with the emphasis on the effects of weir angle to the main channel and weir shape on flow pattern. Flow visualization is carried out using dye injection and oil film methods together with the measurement of three mean velocity components and water depth. With the increase of the weir angle, flow in the main channel tends to move toward the flood plain in the upstream side of the weir, while flow over the weir is apt to attack the main channel side. Strong upward currents move around the weir on the flood plain with shallow water depth, resulting in an oblique hydraulic jump on the flood plain. A large recirculation zone is generated in the main channel at the downstream side of the weir.
