Abstract
A model of a proposed weir for the Richelieu River was constructed and tested. Model scale was 1:9.83. The tests were conducted to obtain the stage discharge relationship and to investigate if the control of the tailwater level will affect the discharge coefficient. It was found that the discharge coefficient was not affected for flows lower than about 40,000 ft3/s. Two modifications to the toe of the weir were tested. Both showed significant reduction in scour of the river bed as compared with the original weir design. A horizontal extension of the weir is the recommended modification. The rip-rap protection was designed and tested and found to be stable for the weir with the recommended extension.
