            up to 10°. The beach extended thereafter, dropping down from about RL 2 m AHD to the shoreline (around
            RL 0 m AHD).
            The abovementioned geomorphological features are illustrated in Text Figure 7 below.

            4.3            Geology
            Available geological information 1 indicates that the site is underlain by Pleistocene age quartz dune sand
            (described as “parabolic dunes”; Ref. extract of published mapping in Text Figure 8). The headlands to the
            north of the site are indicated to consist of materials derived of the Tiaro Coal Measures, a late Triassic to
            Jurassic age sedimentary deposit. These materials are expected to underlie the dune sands proximal to the
            site at depth.
