Dynamic Segmentation in the Coastal Information System
379
for 70 percent of the total population whereas on the south coast the ten most
frequently occurring relationships represented 72 percent of the total population. Eight
of these binary relationships occur in both the east and south coast populations. The
remaining two binary relationships for the south coast are represented by
unconsolidated material whereas the
two unique relationships for the east coast are represented by solid material. These data
also show that of the eight binary relationships common to both areas, the percentage
of adjacency relationships which contain unconsolidated material appears to be higher
in the south coast data set with the exception of unconsolidated beach/solid cliff (bucs).
This tends to support the visual analysis of coastal geomorphologic foreshore and
backshore data from the CIS which suggests a higher proportion of adjacent
unconsolidated forms along the south coast.
Along-shore and across-shore tertiary sequence relationship data were
tabulated separately for the south and east coasts and are presented in Fig. 4. Because
of the large number of unique relationships, the data were combined into four
categories:
solid/solid/solid
relationships
(s/s/s),
solid/solid/unconsolidated
relationships (s/s/u), unconsolidated/unconsolidated/solid relationships (u/u/s) and
unconsolidated/unconsolidated/unconsolidated relationships (u/u/u). Tertiary s/s/s
relationships appear to predominate along the east coast. Meanwhile, s/s/u
relationships tend to occur at a similar frequency on both the east and south coasts.
Conversely, u/u/s
