Students spend the day travelling from the Northern to the Southern end of Warilla Beach, learning the biophysical processes that led to the erosion and shoaling issues and they follow four management strategies that are being implemented to address issues at various locations along the way.
Inquiry and focus questions
How do environments function?
How do people’s worldviews affect their attitudes to and use of environments?
What are the causes and consequences of change in environments and how can this change be managed?
Why is an understanding of environmental processes and interconnections essential for sustainable management of environments?
How are sand dunes formed and stabilised by vegetation?
Fieldwork technique: students work in groups to complete a transect to measure and record key vegetation and physical factors at three locations from the incipient dune back.
How do the natural processes of erosion and deposition shape coastal landforms?
Fieldwork: Observing and recording longshore drift and the influence of constructive and destructive waves.
How do we analyse the effect of interactions and connections between people, places and environments?
Fieldwork: Students create a precis map to show influence the groyne has upon the movement and deposition of sand through longshore drift and the subsequent shoaling of Elliott Lake entrance.
Students prepare a line drawing to show the groyne, seawall and bridge. They annotate the line sketch to describe the purpose of each, then critically assess the impact of the seawall upon the rate of beach erosion.
Students critically analyse management strategies to ensure: the protection of the unique grassland habitat of Windang Island; enabling controlled access to and from the beach; protecting houses and property from rising sea levels and overtopping of the seawall during storms; reduced infilling of Elliott Lake entrance by the infilling of sand via longshore drift.
Why does Warilla Beach experience an annual net loss of sand?
Students label a map of Warilla Beach to show their route and salient features observed during the excursion.
Students undertake a summative task by answering the question as to why natural processes of deposition are inadequate in replenishing sand lost from Warilla Beach.
