Abstract: Results of a series of laboratory experiments in a flume to determine the conditions under which floating ice floes are entrained into a submerged outlet are reported. Entrainment is found to occur when a Froude number based on outlet velocity and submergence depth is exceeded and that critical Froude number is a function of the ratio of outlet height to upstream flow depth. The critical Froude number is also shown to asymptotically approach the Froude number corresponding to equilibrium accumulation thicknesses of ice floes at a surface obstruction as the outlet height approaches the flow depth. Interpretation and application to the design of submerged outlets are discussed.
