Figures 4-44a and 4-44b summarize orientations of the inlet entrance from
1993 to 2004. The aerial photograph of 16 April 2002 approximates the location
and orientation of the channel at the time of the bathymetry survey of 6-8
October 2002. Change in location and morphology of the Goldsmith Inlet
channel entrance between 6-8 October 2002 and 16 April 2003 is substantial.
Sediment accumulation extended the beach 60-80 ft for the 500 ft directly east of
the jetty, and the entrance channel mouth migrated 350 ft to the east. The
effective greater length of the channel diminished the flushing capability of the
inlet and contributed to closure. The acute angle of the inlet relative to the
shoreline, in contrast, allows for more effective sediment bypassing. An
emergency dredging at Goldsmith Inlet took place on 22-26 March 2004, and the
inlet entrance and channel were repositioned.
