Abstract: Tests were conducted in 1:36-scale section models of the high and low bays to develop guidance for rehabilitation of the existing stilling basin, to develop guidance for the safety of survey boats operating in the approach to the structure, and to evaluate characteristics of debris passage through the structure. The portion of the basin between the baffles and end sill was protected with sloping modules constructed of steel and grout, and tests were conducted to determine the hydraulic forces acting on the modules. A flow spoiler design to reduce uplift forces on the modules and not increase the sliding and uplift forces acting on the stilling basin was also investigated. Survey boat safety tests indicated that a typical survey boat operating upstream of the gate bays should be safe with gate openings equal to or less than 30 percent of the head on the crest.
