Abstract: Oxygen transfer into water at low-drop weirs was studied by using a prototype-scale, recirculating hydraulic flume with a weir width of 0.61 m, and a downstream channel width of 1.22 m. An enhanced-oxygen environment was ...

Abstract: The aeration performance with respect to oxygen transfer of a smooth weir, a cobble-faced weir, and a cobble-faced chute was investigated in a large laboratory flume. The maximum difference between upstream and downstream ...
