2) Jolicoeur et al. (1984) examined the use of various trenching patterns in a river meander to prevent ice jam formation, and several patterns were tried that spanned the 36-meter (120-foot) river width (Figure 3-1). The test reach was approximately 600 meters (2000 feet) long. They found that any pattern that crosses from bank to bank was effective, though the herringbone pattern (pattern 1) broke into the smallest ice pieces. In contrast, simply cutting slots parallel to the bank (pattern 6) did not assure breakup of the ice cover.

This remaining brash ice cover then is flushed out by the spring freshet, thereby preventing an ice jam. In some locations simply breaking the ice cover is not sufficient, so icebreaking is often accompanied by clearing the iceout of the problem reach as well. Ice can be cleared by breaking the ice cover, starting at a downstream open water area and progressing upstream into the solid cover, relying on the river flow to carry the ice away. If the pre-freshet flow is not sufficient to clear the ice, it may need to be cleared after it is broken by use of icebreaking ships, towboats, or excavation equipment.

This nine-fold increase in cutting efficiency of the BRQ10-2 suggests that the steam jet is not melting the ice, but is eroding the ice from the jet velocity. Figure 3-5.
