Abstract : This technical note describes methods for selecting appropriate equipment for use in dredged material containment areas. It also briefly describes the types of equipment currently being successfully used in these areas. Management of confined upland dredged material containment areas, to dewater the material and improve its engineering properties, requires use of large equipment for activities such as surveying, trenching, and earthmoving. Because dredged material enters the containment areas as a slurry and subsequently is dried to form a stiff crust overlying softer material, its structure poses many challenges not normally encountered in conventional earthwork. Therefore, selection of equipment must be made based on not only the normal considerations for equipment selection (i.e., use, availability, and capacity), but also on dredged material site conditions. Techniques for assessing equipment mobility and performance have been developed and documented. Empirical data also can provide some initial guidance on equipment selection and timing of initial management activities.
