Potamology ReportSummary: Bank recession has been active at both Free Nigger Point and Point Menoir over a long period of time. A large bank failure and subsequent levee crevasse occurred at Free Nigger Point in March 1949, and an extensive soils investigation was conducted immediately thereafter. The results of that investigation were presented in a report entitled "Investigation of Free Nigger Point Crevasse, Mississippi River," Waterways Experiment Station, December 1950. An investigation of soil conditions at Point Menoir (a bendway similar to Free Nigger Point) was conducted in 1950 and 1951, using undisturbed sampling techniques and special laboratory tests developed since 1949. A limited number of additional undisturbed and sample borings were also made at Free Nigger Point using the improved procedures to afford a valid comparison of soil conditions at both sites. This report presents a summary of the soil conditions at the two sites, a comparison between the sites, and predictions of the future stability of the sites.
