Shorelines naturally move through waves and tidal movement. Darwin has large tidal ranges averaging over 8m a day. This movement in conjunction with sea level rise causes natural erosion to our coastline. Identifying opportunities to mitigate against these processes is an ongoing task for City of Darwin.
We take a long term approach to managing the shoreline of Darwin Harbour within the Darwin Municipality. This is achieved through:
- Identification of sites and infrastructure at risk
- Identification of corresponding actions to prevent erosion and rehabilitate eroded areas
Both the immediate and long-term management of localised coastal erosion is outlined in our Coastal Erosion management plan.
Outcomes from the plan have included the Nightcliff seawall and rockwalls.
