Kakadu sea level rise risk - Stage 1 and 2 Sea Level Rise (SLR) model outputs
The low-lying coastal floodplains of the Kakadu Region in tropical Northern Australia encompasses World Heritage Kakadu National Park and are highly vulnerable to future sea level rise (SLR) and extreme weather events, yet there are no modelling tools to assess potential impacts of saltwater inundation (SWI) on freshwater ecosystems and to evaluate... more future management options.
This collection contains the stage 1 and stage 2 model outputs from this project.

sea level rise
A tidally-driven hydrodynamic model was developed to simulate the frequency and extent of SWI in the Kakadu Region for four mean SLR scenarios: 0 m (Present-day 2013); 0.14 m (2030); 0.70 m (2070); and 1.1 m (2100). Simulations were undertaken at 60 m spatial resolution using October dry season tides, and a Digital Elevation Model (0.10 m vertical resolution) constructed from LiDAR point cloud data was used to resolve coastal and river system terrains. Model outputs (maximum extent and frequency of SWI) were used to assess potential loss of freshwater floodplains for each scenario at a park-wide scale and for three case study areas that differ in tidal influence.
