Natural disasters, such as coastal hurricanes and rainfall flooding, can create major impacts on marine transportation. Ports and port cities will also be increasingly threatened by tsunami and climate-related sea level rise (SLR) by year 2100.  

This paper presents computer modeling and geospatial analysis of these natural disaster risks and resilience management strategy using a case study of Port city of Miami. Our computer simulations show that tsunami and sea level rise create more inundated land area than extreme rainfall flooding.

They also indicate that a population of 1.42 million is at risk in metropolitan Miami and surrounding areas. Hardening of port infrastructure assets in the area is recommended to enhance resilience against coastal disasters and minimize supply chain disruptions. About90% of global imports and exports are
