This Coastal Engineering Technical Note CETN demonstrates how to estimate maximum scour potential when ebb flow is deflected by an inlet navigation jetty. Scour hole formation adjacent to the channel-side toe of protective inlet jetty structures is a troublesome problem at some navigation inlets. Without remedial action, continued scour hole growth may result in jetty instability and partial collapse of the structure. In addition, deep scouring adjacent to the channel side of a protective jetty may be accompanied by shoaling of the maintained navigation channel, shifting the de facto navigation channel dangerously close to the jetty.
