ABSTRACT
The present paper compares the variations of storm surge resulting from Hurricane Andrew in 1992 and Hurricane Irma in 2017 at Miami, Florida, using two different computational models, i.e., ADCIRC (ADvanced CIRCulation model) and SLOSH (Sea, Lake, and Overland Surges from Hurricanes).

When made landfalls in Bahamas and Florida in August 1992, Hurricane Andrew was a category 5 hurricane on the Saffir/Simpson Hurricane Scale. It brought devastations along its path including Bahamas, southern Florida, and south-central Louisiana. Hurricane Irma was also categorized as a category 5 hurricane along its path, devastating Porto Rico, Dominic Republic, Cuba and southern Florida in September 2017.

This study investigates the storm surge level corresponding to these two major hurricanes at coastlines of Miami, the largest metropolis and growth center in southern Florida. In this study two numerical models for storm surge are utilized. The ADCIRC model is a two-dimensional, hydrodynamic circulation model developed by ADCIRC Development Group which included universities, consultants and the United States Army Corps of Engineers. The SLOSH model is a two-dimensional operational storm surge model developed by National Oceanic and Atmospheric Administration.

The ADCIRC and SLOSH models results for storm surges caused by Hurricanes Andrew and Irma, at Miami coastlines are presented and compared against observations.
