"A Storm Hazard Matrix combining coastal flooding and beach erosion"
Consider these two locations. Did they face the same type of coastal storm hazard? A thread 1/7
Coastal #storms and #hurricanes can bring flooding (elevated water levels) and beach #erosion, but how much of each depends the coastal setting and the storm conditions. If we can understand and predict what hazards may threaten a coast, we can better prepare for them. 2/7
Coastal flooding and beach erosion hazards on sandy beaches should be considered separately. We're building off the existing Storm Impact Scale and proposing a new erosion hazard scale which is based on changes to the beach and dune profile. 3/7
The overall impact of a storm, based on the combination of flooding hazard and erosion hazard regimes, can then be described using our new Storm Hazard Matrix. Empty cells represent combinations unlikely to occur on sandy beaches. 4/7
To show how the Storm Hazard Matrix can be applied, we look at two extreme regional-scale storm datasets: 1) NSW, Australia 2016 East Coast Low (dominated by erosion hazards) and 2) Santa Rosa Island, FL, USA 2004 Hurricane Ivan (dominated by flooding hazards). 5/7
We show that our Storm Hazard Matrix approach which considers both flooding and erosion hazards can give better insights into the nature and magnitude of storm impacts. This is a promising approach if we're trying to forecast coastal storm hazards at a regional-scale. 6/7
This manuscript has currently been submitted for publication so we welcome any comments and thoughts in the meantime. doi.org/10.31223/X5Q592 7/7
