Expansive Clay Minerals and Hurricane Katrina
In 2005, Hurricane Katrina landed on the southern states of the U.S. and caused more than 1000 deaths and severe property damage. The life loss and property damage were mostly caused by the failure of floodwalls that surrounded City of New Orleans. Several cases of failures were caused by so called "gap formation" and "erosion" which were believed to be due to the dispersive characteristics of expansive clay minerals contained in levee soils. The New Orleans area has wide distribution of expansive clay minerals. Some soils in this area contained as high as 5% montmorillonite soils. In this study, it turned out that the undrained shear strength and erosion resistance of these soils can drop as low as immeasurable range when wet. This paper experimentally and analytically addresses the behavior of expansive soils contained in levee soils that triggered the failure of the levees under heavy rain and overtopping condition.
