Significant land inundation only occurs for scenarios modelled with the largest waves (9.0 M_W source). The degree of exposure to the open ocean and the geomorphology of locations within the Harbour determine the relative level of these impacts. Narrow, shallow channels, even those sheltered from the open ocean, create a bottleneck effect and experience the highest relative current speeds as well as elevated water levels. The largest maximum water levels (>8 m) occur in exposed, funnel-shaped bays and wave amplification is greatest at locations exposed to the open ocean: >7 times deep water wave heights for 9.0 M_W source waves. Upstream attenuation rates of runup and maximum water level show a linear correlation with wave height parameters at the 100 m depth contour and may provide some predictive capabilities for potential tsunami impacts at analogous locations. In the event of a tsunami in Sydney Harbour, impacts may threaten marine traffic and infrastructure.]]> Thu 16 Jan 2020 13:25:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18643 Mon 20 Jul 2015 16:52:13 AEST ]]>
