A Review of Tropical Cyclone-Generated Storm Surges: Global Data Sources, Observations and Impacts

Research dates: 2008-2014

Investigator(s): Hal Needham, Barry Keim, Amanda Lewis (Billiot)

This study provided the first comprehensive literature review on global storm surge data sources, observations and impacts. We utilized literature from governments, peer-reviewed journal articles and newspaper archives to document global storm surges since 1880. This work identified the location and height of more than 700 storm surges, the majority of which were located in the Western North Atlantic (U.S. and Caribbean), Western North Pacific (East Asia), Northern Indian Ocean, and Australia/ Oceania. We are developed a global surge map and database to spatially reference these events.

A Location-Based Storm Surge History for the U.S. Gulf Coast

Research dates: 2008-2014

Investigator(s): Hal Needham, Barry Keim, David Sathiaraj, Amanda Lewis (Billiot)

The SURGEDAT database has now archived more than 5,200 high water marks from tropical surges along the U.S. Gulf Coast. A Web tool that utilizes these observations to provide location-based storm surge histories for coastal locations was created. This tool provides a complete list of large and small surges from South Padre Island, Texas, along the Gulf Coast to the Florida Keys. Please contact us if you’re interested in beta-testing this product.

Storm Surge Return Levels for the U.S. Gulf Coast

Research dates: 2008-2014

Investigator(s): Barry Keim, Hal Needham, Amanda Billiot Lewis, David Sathiaraj

SURGEDAT’s comprehensive storm surge archive provides a unique opportunity to estimate coastal flooding frequencies. SCIPP researchers used data-driven statistical methods to estimate storm surge return levels, such as the height of the 100-year or 50-year storm surge, in specific locations. We have now completed a preliminary study that analyzed data for 26 Gulf Coast locations.

Calculating Storm Surge Return Periods Along the Gulf of Mexico

Research dates: 2008-2015

Investigator(s): Hal Needham, Barry Keim, David Sathiaraj, Amanda Lewis (Billiot)

The primary goal of this research was to identify maximum storm surge height and location of peak surge for storm events occurring between 1880-2013 along the U.S. Gulf Coast. More than 80 sources of information including more than 3,000 pages of newspaper have been used to construct the database that includes just under 200 surge events. The data are stored in a GIS database that outputs maps according to surge height, year, and/or magnitude. The surge data are also being used to calculate return periods for extreme surge levels along the Gulf Coast region.


A Storm Surge Database for the U.S. Gulf Coast

Research dates: 2010-2013

Investigator(s): Hal Needham, Barry Keim

Tropical cyclone-generated storm surges are among the most deadly and costly natural disasters to impact the United States. SURGEDAT identifies the location and height of peak storm surge for 195 surge events since 1880. A total of 62 sources were utilized to construct this dataset, including 28 Federal Government sources, numerous academic publications, and more than 3000 pages of newspaper from 16 daily periodicals. SURGEDAT will be valuable to coastal stakeholders, including planners and emergency managers, coastal scientists, and the hurricane and storm surge research communities.
