This report presents results of the research for MMS Project 552. It includes locations of known mudslide damage caused by hurricane Ivan. It also includes descriptions of data used to analyze the mudslide hazard in the Mississippi Delta region of the Gulf of Mexico, including Hurricane Ivan wave hindcast data, bathymetric data, and soil shear strength data. A limit equilibrium method used to analyze the data is described and presented in two practical forms: a chart that can be used to find the factor of safety against mudslide initiation for a site where the undrained shear strength increases linearly with depth, and an Excel spreadsheet computer program that can be used to calculate the factor of safety for sites with more complicated shear strength profiles. A regional analysis of the data is presented, including ranges in factors of safety for the mudslide locations using all the available shear strength profiles in the Mississippi Delta region of the Gulf of Mexico. Site specific analyses are presented where site-specific shear strength data were available, and a parametric analysis is presented for a site in the Mississippi Canyon lease block 20.
