Coastal hazard assessment for Miami and its surrounding areas in Florida

C oastal areas are prone to many natural hazards such as extreme rainfall floods, sea level rise (SLR), and tsunami. Miami
is known as the most vulnerable areas to weather related natural disaster in the United States due to its low elevation and
being surrounded by ocean.The primary objective of this presentation was to present the Hydrologic Engineering Center’s River
Analysis System (HEC-RAS) floodplain modeling, Center for Advanced Infrastructure Technology (CAIT) SLR simulation,
and CAIT tsunami simulation using high resolution laser-based digital elevation model data of the terrain and Landsat-8
imagery to evaluate the impact of extreme rainfall floods, SLR, and tsunami on Miami and its surrounding areas. The CAIT
tsunami simulation methodology was motivated from the 9m tsunami wave peak height (WPH) that hit the Kesennuma Bay
in Japan on March 11, 2011. The key results of the HEC-RAS floodplain modeling indicate that 409.64km2, or 56.76% of the
land area is inundated by floodwater. The affected population due to an extreme rainfall flood is around 1.42 million. The
results of the SLR simulation show that the submerged land due to 2m SLR is 411.96km2 (57.08% of the land area). The affected
population from a 2m SLR is 1.43 million. Results of the tsunami simulation show that 703.05km2, or 97.41% of the land area is
submerged by the 9m tsunami WPH. The affected population from the 9m tsunami WPH is 2.40 million. This study indicates
that floods caused by rainfall or tsunami in a short period of time affect a larger inundation area than the submerged area
caused by SLR simulation for year 2100 gradual seal level rise. A resilience management plan was also recommended to protect
people, infrastructure from the coastal hazards.
