sand dunes

The beach is more than a space for people to walk, sunbath and swim. It has a past and a future  and this indicates  that  the sand dunes and the fragile dune  vegetation are in  need different forms of coastal protection and management.   Hence the use of both sand-drift fencing to help restore and protect dune systems from erosion, by trapping wind-blown sand in the vicinity of the fence where natural vegetation is not sufficient to do so effectively, and various  revegetation and restoration projects.

Beaches have a history and for Adelaide’s coastal beaches this history  is one of coastal degradation.

Prior to European settlement, the beaches were naturally replenished from the dunes and the southern beaches,  and therefore sand movement could continue almost indefinitely. Predominant wave energy hitting beaches from the southwest naturally shifted sand in a northerly direction along the coastline with most of the sand accumulating at Semaphore and North Haven. Development along our coast however, has resulted in large quantities of the sand supply either being ‘locked up’ (eg., ate the harbours at Glenelg and West Beach) or removed from the beach system, preventing natural replenishment.  As a result, natural processes and coastal storms have continually eroded beach width, and without artificial replenishment, the sand will continue to erode away, exposing the underlying hard rocks and clays.

Past futures: the beach

Past Futures is the working title for the third section of The Bowden Archives and Other Marginalia. This section maps the space outside of Adelaide’s CBD and Bowden-Brompton. It represents an escape from the confines of  the city, sometimes in  the form of  day trips to the Adelaide Hills and Mt Lofty Ranges; trips to Melbourne and along the River Murray.

Escaping the confines of Bowden  during the summer heat was necessary and I would often go to Adelaide’s coastal beaches in the late afternoon. I would usually park the Kombi at  Largs Bay in the late afternoon and walk along the flat open stretch of sand to North Haven and back with Fichte, my standard poodle.

This was a time when people sunbathed  on the beach and they didn’t really worry about effective sunscreen to prevent melanomas and skin cancer, even though the Slip, Slop, Slap!  health campaign was launched in 1981 by the Cancer Council as part of its SunSmart campaign.    The beach was a hedonistic holiday zone–a shared space of relaxation–with minimal shade from the burning sun.
