Abstract
The Western Australian tide gauge network was used to examine coastal flooding occurrence. Astronomical tides and storm surges were confirmed as the primary contributing processes with other processes having a secondary influence. Coastally trapped waves generated by tropical cyclones were identified, propagating thousands of kilometres from the Northwest Shelf. Inter-annual modulations on coastal flooding included the ENSO cycle and the 18.6 year tidal cycle for the southwest, next peaking in 2025. A 4.4 year tidal cycle occurs in the northwest. Results confirmed the importance of Interactions between coastal flooding processes and showed potential for extreme flooding if processes peak simultaneously.
