Abstract: Field jet erosion tests (JETs) were conducted by the U.S. Army Engineer Research and Development Center (ERDC) to assess the erodibility of two enlargement segments within the Mississippi River Levee (MRL) Collocated Demonstration Section in Plaquemines Parish, Louisiana. The first segment was constructed of Bonnet Carré clay with a fly-ash/bed-ash blend treatment, and the second segment was constructed of Bonnet Carré clay treated with lime. In addition, a section of untreated clay on the original levee was also tested. Overall, the field JET data showed that the clay treated with lime was categorized as resistant to very resistant. The fly-ash/bed-ash-treated clay was categorized as moderately resistant and resistant. When compared to the existing, untreated clay levee, both treatments reduced the erodibility of the soil. However, the field JET results showed that lime treatment performed better than the fly-ash/bed-ash treatment.
