DESIGN CONSIDERATIONS FOR LATERAL SEEPAGE CONTROL: This technical
note includes discussion of design elements for lateral seepage control systems, including slurry
walls and sheet-pile walls. All involve installation of a low-permeability core in the normal dike
of a CDF. The information on slurry walls and sheet-pile walls is from "Design Guidance for
Applications of Permeable Barriers to Remedy Dissolved Chlorinated Solvents," DG 1110-
345-117 (USACE 1997). Detailed discussion of dike design and construction within which the
aforementioned lateral control features may be employed is provided in USACE (1987).
