Flood risk management in the United States and the impact of Hurricane Katrina

Open access
Galloway, Gerald E.·2008·International Journal of River Basin Management

Abstract

In 1993, the United States experienced a flood that produced the highest economic damages of the century Large areas of the Midwest were underwater for weeks as the Missouri and Upper Mississippi Rivers left their banks. Over 130 people lost their lives and flood losses grew to over $20 billion (US). For a few years after, national attention was focused on floodplain management, but, as other issues faced the government, efforts to develop a new approach to dealing with flood losses faded. Hurricane Katrina, with the deaths of over 1300 persons and billions of dollars in damages, brought flooding back to the front page of the newspapers and has stirred a new interest in developing a more rational approach to occupance of the floodplain and to use of new approaches to flood damage reduction. As a result of several recent studies and government actions, attention is now being focused on the use of risk analysis methodologies to support decisions on floodplain use, slowly edging the United States closer to flood risk management and away from floodplain management. This paper discusses the lessons learned from the 1993 flood, the actions taken in the United States since 1993, and the impact Hurricane Katrina is having on bringing risk into the decisions that shape floodplain use in the United States.

TL;DR

This paper reviews US floodplain management before and after Hurricane Katrina, arguing that the country is slowly shifting from floodplain management toward flood risk management. It uses the 1993 Mississippi flood and post-Katrina forensic and policy efforts to show how risk analysis is being incorporated into levee safety, New Orleans protection, and Louisiana coastal restoration decisions.

Key findings

  • The 1993 Mississippi River flood caused over 130 deaths and more than $20 billion (US) in damages, described as the largest economic loss of the century in constant dollars; the 1994 IFMRC report recommended concurrent reduction of flood damage, environmental protection, and economic growth.
  • Hurricane Katrina caused more than 1,300 deaths, over a million people lost their homes and jobs, and estimated direct and induced damages, disaster response, and restoration costs were expected to exceed $100 billion.
  • Post-Katrina, the White House directed USACE and FEMA to begin a national levee inventory and assessment based on risk analysis, requesting $30 million in supplemental appropriations; the IPET draft final report concluded the New Orleans hurricane protection system “did not perform as a system” and recommended risk-based planning and design.
  • Since 1994, nearly 30,000 structures were relocated or removed from the floodplain, but by mid-2002 the US still had three floodplain management poles—risk analysis, the SPF no-disasters approach, and the NFIP 100-year standard—and flood risk management remained “in its infancy” in the United States.

Methods

  • Narrative policy review and commentary synthesizing lessons from the 1993 flood, actions taken since 1993, and the impact of Hurricane Katrina; no formal empirical dataset, sample, or statistical model is described.
  • Draws on government reports and actions, including IFMRC (1994), USACE Standard Project Flood and risk analysis documents, FEMA’s NFIP, NRC reports (2000, 2004, 2006), ASCE External Review Panel reports, the IPET draft final report (June 1, 2006), and the LACPR interim report (July 10, 2006).
  • Main analysis is qualitative historical and policy synthesis comparing floodplain management and flood risk management and tracing the adoption of risk analysis in US flood policy.

Limitations

  • The paper does not state limitations of its own analysis; it reports limitations of the risk-assessment approaches it discusses, including the LACPR report’s note that the risk-based methodology needs further development by leading experts and rigorous independent review, and the NRC panel’s concerns about large uncertainties in probabilities, difficulty estimating failure probabilities due to spatial heterogeneity, and vulnerability of many system components.
  • The author states that moving to flood risk management requires understanding the costs and consequences of failure, but willingness to address the latter was “not yet apparent” within the federal government, and federal NED guidance was said to bias against environmental and social costs.
  • Evident from the text: the paper is a policy synthesis rather than a formal empirical study, relying on secondary reports and the author’s interpretation, so its findings are interpretive and not causal estimates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
