Coastal sand masses (beach ridges)
Click on elements of the model or select from the tabs below
Beach ridges have developed along the Queensland coastline. They are largely comprised of coastal sands and typically support a single, unconsolidated sedimentary aquifer, where groundwater forms a freshwater lens in the intergranular voids of the coastal sand mass. Perched aquifers may also occur over low permeability layers within the sand mass.
Unconsolidated sedimentary aquifers in sand masses may provide a wide range of ecosystems with water required to support their fauna and flora communities, ecological processes and delivery of ecosystem services.
