Biophysical Processes-Erosion
Research Assessment Task 2 - 2013
Biophysical Interactions (Northen Beaches - Erosion)
Luke Sheldrick
Investigate one issue in one of the biophysical components, to illustrate how an understanding of biophysical processes contributes to sustainable management in the environment

The Northern coastline of Sydney is composed of sand and in some places mud, the shoreline is prone to change, building seaward and in some places eroding landward. In some locations this is a natural process with usually little impact on human settlement …show more content…
These are examples of how humans have physically impacted the beach and its structure. The flight deck is a human residential block of units on the edge of the beach. This unit block has massively affected the shaping and the beachfront of that area of Collaroy beach. The coastal processes that are threatening the erosion of the beachfront developments are, Erosion/Accretion Cycle (or sediment budget), destructive storm waves and king tides. These processes are slowly undermining the building and causing the dune under the units to become unstable and dangerous for people living in and around them. Also the salts from the waves blowing onto the units causes the metal to rust and the foundation of the building and balcony handrails to be at risk of being unreliable and …show more content…
Without some Coastal Management Strategies the Narrabeen Lagoon would continuously widen causing danger to the caravan park on the lagoon and local residents. Structures have been put in place not only to help this but also for other needs such as to lower the erosion cause by humans.
Boarded chain walks help set out a path from the car parks to the beach over the Birdwood Park Dune so that we kill minimal vegetation that is keeping the structure of the dune intact. To keep the vegetation up to standard, re-vegetation schemes are put in place so that the dune stays stable and minimal erosion takes place. A training wall on the western side of the lagoon entrance keeps the lagoon in shape and stops any erosion that will be introduced by the widening of the lagoon. After a big storm sand dredging takes place at the entrance of the lagoon to stop the channel from blocking up which will cause a massive change to the lagoon structure. There strategies really help keep the beach as pristine as
