To analyze morphology change for the offshore at Goldsmith Inlet, beach
profiles from the 6-8 October 2002 survey are compared to those from a March
1998 survey (OCTI 1998), spanning a 4-1/2 year interval. Analysis of the
migration of the inlet entrance and the inlet channel, growth of the fillet at the
jetty, growth of an attached west bank fillet, and the flood shoal is conducted by
reference to aerial photography.
Offshore morphology change
Figures 4-41a to 4-41k plot comparisons of 1998 (OCTI 1998) and 2002
beach profiles for the areas offshore of Goldsmith Inlet. In some instances,
profile transects were referenced to previously established monuments (OCTI
1998). East of Goldsmith Inlet, the profiles often did not overlap. The profile
surveys indicate a shoreline near equilibrium from 1998 to 2002.
