| description | <p>Severe tropical cyclone (TC) <i>Debbie</i> made landfall on
the northern Queensland coast of Australia on 27 March 2017 after crossing
the Great Barrier Reef as a slow-moving Category 4 system. Groups from
industry, government and academia collected coastal hazard and impact data
before, during and after the event and shared these data to produce a
holistic picture of TC <i>Debbie</i> at the coast. Results showed the still
water level exceeded the highest astronomical tide by almost a metre. Waves
added a further 16 % to water levels along the open coast, and were
probably unprecedented for this area since monitoring began. In most places,
coastal barriers were not breached and as a result there was net offshore
sand transport. If landfall had occurred 2 h earlier with the high tide,
widespread inundation and overwash would have ensued. This paper provides a
case study of effective cross-sector data sharing in a natural hazard
context. It advocates for a shared information platform for coastal extremes
in Australia to help improve the understanding and prediction of TC-related
coastal hazards in the future.</p> |
