Abstract: This paper describes a two-dimensional numerical study using a dynamic ice transport model to analyze the design and effectiveness of an ice control structure on the Grasse River, Massena, NY. The structure was designed as an L-shape barrier with a flow relief channel along the northwest bank of the river. The effect of the length of the flow relief channel was first examined to assist in the selection of channel length. The ice retention capability of the ice control structure as well as the under ice current and the backwater effect of the ice accumulation were studied. A sensitivity analysis was carried out for several combinations of breakup flow and ice supply conditions with a 100-year return period. The effect of possible ice jam formations downstream of the control structure resulting from the possible ice leakage through the ice control structure was also examined. The findings presented in this paper represent work in progress only, as the final remedy at the Grasse River site has yet to be selected.
