| description 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 water surfaces was 0.7 m. A review of existing relationships to predict aeration at weirs indicated that prototype–scale model studies and actual prototype data were limited in this range of drop heights. In addition, most laboratory testing has been conducted at greater drop heights and lower unit discharges. To reduce experimental uncertainty, a procedure was developed which uses an enhanced-oxygen atmosphere over the flume water surface. The uncertainty in values of the deficit ratio ( | |
