Sea level rise and more intense storms, associated with climate change, and subsidence make Port Adelaide one of the most vulnerable areas in SA for flooding.
Estuary Care Foundation, (ECF) with funding support from Green Adelaide, commissioned Animate Your Science to produce this animated video Port River Seawall to advocate for the community to be protected.
Given the scale of the challenge, to plan and fund a Port River Seawall, State and Federal Government funds will be needed.
The City of Port Adelaide Enfield in March 2020 released a 2018 Coastal and Inundation Modelling Phase 3 Report, which outlined the need to upgrade the Magazine Creek tidal gate and proposed planning for a Port Adelaide Sea Wall in 2020-2025 and construction in 2025-2030. The Council is advocating for the State Government to respond.
The Foundation has, since it was formed in 2016, been concerned about the potential adverse impacts on the community from flooding. The Foundation has advocated eco-engineering responses, where possible, knowing that some hard structures will be needed.
ECF has sought funding for Living Shoreline trials and been funded for a small scale trial in the inner harbour.
The need to protect the community, homes and infrastructure has been documented in our regional climate adaptation plan, AdaptWest.
The Australian Government website Climate Change in Australia provides projections for the future, including scenarios for sea level rise. The diagrams below come the Coast and Marine Chapter of Projections (and Recent Trends) pp152 and highlight why we need to prepare.
