In many localities it is difficult to find suitable confined disposal areas for dredged materials and, even where available, environmental constraints may prevent or restrict their use. This study sought to determine if conventional stabilization techniques can be used to densify/dewater dredged material as a means to increase disposal area storage capacity. This was done on a judgment basis -- without laboratory or field research. This study was restricted to clays and silty clays which have high water contents after placement in disposal areas. It was concluded that conventional stabilization techniques can be used to increase disposal area capacity but economic constraints may restrict their use. Water content, density, and Atterberg limits of fine-grained dredged material in existing disposal areas are inadequately known. A large-scale but relatively low-cost sampling program is recommeded to investigate existing disposal areas of various ages containing various depths and types of dredged material.
