Abstract: Summary The St. Lawrence Seaway Development Corporation in the U.S.A. has been assigned with the task of demonstrating the feasibility of winter navigation on the St. Lawrence River. As a part of this program, an ice boom was designed, installed, and instrumented at Copeland Cut in the Wiley-Donden Canal near Massena, New York. In order to measure forces exerted on the boom elements by the ice cover, twenty tension transducers were designed, built and located in the critical members of the boom. Force measurements were made before, during, and after ship transits through the ice cover and boom opening. Typical signal recording of several of the tension transducers are presented. It was concluded that, within the flow velocities experienced at the test site, an ice boom with a navigation channel is feasible. Ship induced forces were found to be relatively small compared to steady state forces and they were limited primarily to the gate float area. It was also found that, the effect of the water surface elevation fluctuations must also be considered during the design when it is necessary to anchor the shoreside ends of boom cables well above the water level.
