DISCUSSION: This CETN has described general horizontal circulation patterns common to
most inlets. These patterns will vary according to the geomorphology, dredging practice, jetty
alignment, and tidal forcing, among other factors, at the particular inlet.
It has been shown that the horizontal circulation is often known or can be predicted with
sufficient accuracy to reduce or mitigate scour, improve channel alignment, and qualitatively
predict sedimentation patterns. Such predictions can be performed in numerical models
(Militello 1998) and physical models (Seabergh 1999).
