Book Description
Several alternatives were investigated to replace or extend the 2,500-acre Craney Island Disposal Area for continued dredged material disposal for the Norfolk harbor and channels. The disposal area was completed in 1957 and has been used continuously since that time and the dikes have been raised several times to the present e1 +26 ft Mean Low Water (MLW). Because of new plans to deepen the existing channel and continued maintenance dredging, the estimated storage life has greatly reduced. Five alternate configurations of the extension of Craney Island to the west and/or north were investigated as to their estimated storage capacity, their effect on the hydrodynamics of the harbor and river system, and the stability and constructibility of the retaining dikes which is the subject of this report. It was determined that: 1) it is technically feasible to design and construct the required dikes to e1 +8 ft MLW by hydraulic placement of sand; and 2) these dikes could be protected from erosion by the placement of riprap on the inside and outside slopes. The most economically feasible alternatives for storage capacity were configurations 5 and 2 which had an estimated cost per cubic yard of storage of $0.58 and $0.70, respectively. Keywords: Dike stability.

Book Description
The Craney Island disposal area is a 2500-acre confined dredged material disposal site located near Norfolk, Virginia, one of the largest such sites in the Nation. The purpose of constructing such a diked disposal area is twofold: (a) to provide adequate storage capacity for dredged material over the design life of the facility and (b) to provide adequate sedimentation of dredged solids to maintain water quality of effluent.
