N2 - In March 2019, floodwaters on the Missouri River reached within 12 in. (0.3 m) of the top of the levee and led to underseepage distress to the Lake Waconda Levee resulting in internal erosion of the foundation soils, as evidenced by sand boils and seepage areas at the landside levee toe. A 1, 900-ft (579.5 m) riverside seepage barrier was designed and constructed using the one-pass trench mixing method to remediate underseepage distress where the thin clay blanket included clean and silty sand strata interbedded with the fine-grained material. The one-pass method has not been previously used on federal levees, so a robust quality control (QC) and quality assurance (QA) testing program was specified, including supplemental subsurface explorations along the alignment, a full-scale test section, laboratory testing, and confirmatory coring. The design and results of the wall construction are presented.
