Abstract : Submerged weirs, for modification of the discharge capacity of the St. Clair River, are expected to be constructed of 50- to 90-lb stone with face slopes of about 1 on 1 capped with either vertical-faced precast concrete units or relatively large cover stone. The adequacy of these weirs to withstand the combined effects of riverflow and propeller wash from passing ships was investigated by means of a 1:20-scale section model. A mathematical expression describing the submerged-flow discharge characteristics of the weir investigated is presented in addition to the graphical presentation of basic data. (Author)
