Book excerpt: Primary emphasis of Task 5A research was oriented toward dewatering fine-grained dredged material resulting from maintenance operations and placed in confined disposal areas. Based on results of research, as synthesized herein, it was determined that: (a) Use of progressive surface trenching concepts to remove disposal area ponded surface water and precipitation and enhance evaporative dewatering of fine-grained dredged material is the most cost-effective dewatering alternative. (b) When existing constraints make it impossible to implement a surface trenching dewatering program, a surface trenching program alone will not produce dewatering at necessary rates, or it is desired to obtain maximum possible dewatering effects, various concepts of either gravity- or vacuum-assisted under-drainage may be applied. (c) Implementation of any program of fine-grained dredged material dewatering and densification will be conducted most effectively as part of an overall confined disposal area management plan. The main technical unknown in application of concepts synthesized in the report is the exact rate at which dewatering will occur. State-of-the-art prediction methods given and referenced in the report are satisfactory for feasibility determinations, and, in many instances, use in final design.
