UAB: Coupled Hydrodynamic and Geospatial Model for Assessing Resiliency of Coastal Structures Under Extreme Storm Scenarios

“Globally, the intensity and frequency of coastal flooding during extreme storm events are increasing due to climate change and sea-level rise”, which is resulting in significant damage to public properties, infrastructures, and services. The hydrodynamic effects of flooding during extreme storm events are the leading cause of structural damage to impacted properties and due to their complexity, it is difficult to accurately estimate structural damage and flood vulnerability.

This paper presents a detailed study of a proposed flood induced building-level damage estimation model for a coastal town (Brick Township) in New Jersey, U.S. using Hurricane Sandy as a historical extreme storm event.

A team of researchers collaborated on this study, including Dr. M.H. Motamedi, BaseHealth, Inc., Dr. Rouzbeh Nazari and Dr. Md Golam Rabbani Fahad, Department of Civil, Construction and Environmental Engineering, School of Engineering, and Dr. Maryam Karimi, Department of Environmental Health Sciences, the University of Alabama at Birmingham School of Public Health.

This work is a holistic approach to quantifying building-level damage from flooding. The Geographic Information System (GIS) framework developed during this research can serve as a resiliency tool for coastal communities as well as a centralized database system for targeted risk and resiliency assessments. The results of this study and the case study will inform local municipalities and coastal building designers, to improve building codes and increase the resistance and resiliency of the flood zone building stock and ensure faster community recovery after major storm events.
