Detailed Design for Dyke Marsh Demonstration Area, Potomac River, Virginia
Results of detailed engineering studies regarding use of dredged material to expand an existing marshland area are presented. Sampling and testing programs are described that allowed determination of the suitability of channel sediment for use as marsh substrate. Foundation studies indicated conditions at the demonstration site are adequate for construction of a containment facility. A methodology for correlation of in situ channel sediment volume and containment area volume is presented. The methodology incorporates basic principles of containment area volumetric sizing and accounts for consolidation of the newly placed marsh substrate. Laboratory tests using a full height column were performed to simulate the sedimentation phase of the dredging process. Conventional consolidation tests were then performed on samples taken from the column for evaluation of the consolidation phase. Evaluation were made regarding containment sizing for retention of suspended solids, containment area operation, and procedures for placement of dredged material. Results of retaining dike stability analyses, dike settlement analyses, and erosion protection requirements are presented. Availability of construction materials for the containment facility and recommended construction procedures are described.
