Water Displacement From Ship Causes Mini Tsunami In Canal

Even small increases of speed of only a few Knots can greatly magnify the effects of tidal bore exponentially (an increasint log when graphed) due to water being a “non compressible medium”.

The displacement effect in this video is being caused by a 1000′ long Freighter heading northbound on the St. Clair river, running at 4 knotts over the allowed speed of travel early in the shipping season.

This ship leaves large displacement that damages creeks and feeder streams.
