Special Geotechnical Lecture at ASU - Katrina Levee Failures

SPECIAL GEOTECHNICAL LECTURE
Monday, February 1 LSE 106
Reception 5:30 - 6:00 PM: Lecture 6:00 – 7:00 PM
KATRINA AND LEVEE FAILURES BY OVERTOPPING
Jean-Louis Briaud, Ph.D., P.E.
President, The Geo-Institute of ASCE
Professor and Holder of the Buchanan Chair
Zachry Department of Civil Engineering, Texas A&M University


On August 29, 2005, Hurricane Katrina landed a devastating blow to New Orleans and its surroundings. Levees and bridges failed and about 1500 people died. The engineering aspects of this disaster are presented with particular emphasis on levee overtopping and associated erosion, which was the cause of about 80% of the levee failures. An NSF sponsored study undertaken to evaluate the resistance of levees to overtopping is presented including sampling of the levees around New Orleans and associated erosion susceptibility testing. A methodology that was developed to take the overtopping into consideration in design issue and thereby reduce the risk of failure by overtopping in the future will also be presented. Other related levee situations around the country such as the Upper Mississippi floods of June 2008 and the evaluation of the California levee system are discussed to paint the national picture. A risk approach to levee overtopping management is proposed.

Here are a couple of studies to look over before you folks get the wrong word on those levee failures in New Orleans on 8/29/05.

Thanks for those links - is there really disagreement with the study that Dr. Briaud is going to present about?

I've seen presentations by Dr. Rogers and it sounded to me like the reasons for levee failure are pretty clear.
