Figure 6.
Postinlet morphology of Chatham Harbor, 7 May 1987
The north and south beach spits continued to recurve as the inlet throat widened.
Figure 7 shows the inlet 17 months after formation on 5 May 1988. The main ebb
channel had migrated to the south and the swash platform on the north end of the
ebb shoal had enlarged. The north barrier spit had recurved north-westward into
the bay. The south spit continued to recurve westward into the bay. The south
beach spit had been described as having five cycles of spit evolution between
1987 and 1989, with spit elongation into the bay, narrowing of the spit and
breaching of the spit end (Weidman and Ebert 1993). Sand from this breached
spit end was incorporated into the complex south flood shoal sand body.
