Modeling the Drying of Dredged Material
The drying of dredged material was modeled mathematically as a diffusive process and the governing equation was solved using an integral method. Closed form solution equations are presented...
Engineering for Beach Restoration Dredging
Beach restoration utilizing offshore dredging has proven to be the most economical way to restore beaches in Florida. There have been over a dozen projects constructed using this method...
Dredging Permit, a Case History
A case history of the federal, state and local permitting process for the dredging and disposal of dredged material of a tanker/barge terminal in Boston Harbor is discussed. The dredging...
Cost-Effective Design for Urban Lakes Dredging
The design of a dredging project for an urban lake is usually more complex than for lakes in rural areas. Three areas are special problems particular to the urban lake: chemical quality...
A Biogeochemical Evaluation of Disposal Options
This paper briefly reviews some of the factors that should be considered in selecting an environmentally sound disposal method for contaminated sediments on the basis of the biogeochemical...
REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...
Evapoconsolidation in Fine-grained Material
The increased difficulty of obtaining land needed for confined disposal of dredged material and phosphatic clays highlights the need to assess alternative disposal measures by accurately...
Marsh Creation Impacts - Mississippi River Delta
Significant conversion of marsh to open water is occurring in the Mississippi River Delta. Evidence is presented that marsh is more valuable to fish and wildlife resources than open water;...
The Maryland Dredge and Fill Permit Process Handbook
Safe navigation in the waters of the State of Maryland is made possible, in part, by the continued maintenance dredging of the State's many ports and waterways. Dredging projects...
Case History: North Slope Alaska Hydraulic Dredging
Alaska's North Slope Borough, with the aid of dredging machinery consultant Michael Weston, and geotechnical consultant Rittenhouse-Zeman & Associates, has pioneered...
Environmental Management Problems of Dredged Material Islands in the Tampa Bay Area
Between 1977 and 1982, four new islands were created in Hillsborough Bay as part of the Tampa Harbor Deepening Project. The islands are now 3-7 years old. They exhibit striking differences...
Activity-Based Evaluation of Potential Bioaccumulation from Sediments
Sediment bioaccumulation potential evaluations can be improved by a two-level approach. Chemical analysis of sediment interpreted using phase-activity considerations in first-level evaluations...
Dredged Material for Backbarrier Salt Marshes
Gulf Coast barrier islands, especially those fronting the Mississippi River Delta, are eroding at a rapid rate. Natural subsidence caused by consolidation of Recent deltaic deposits and...
Aquatic Bioassays in Dredged Material Management
Dredged material ranges from gravel and coarse sand to fine silts and clays, and may be free of contaminants or highly contaminated with a variety of chemicals from industrial, municipal,...
Environmental Legislation Impact on the Port of New York and New Jersey
Environmental legislation since 1972 has resulted in an extensive evaluation of dredged material disposal alternatives for New York Harbor navigation projects. Consideration has been given...
Reliability Analysis as Reflected from the Fourth International Symposium on Stochastic Hydraulics
Reliability analysis is perhaps one of the most practically important branches of the general field of stochastic hydraulics. Its potential applications include quantitative evaluation...
Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...
Movable-Bed Model Investigation of Littoral Drift on the Intake and Outlet of Lin-Kou Power Plant (I)
The establishment and operation of a distorted movable-bed model of the cooling water intake and outlet is described. The model employed is a three-dimensional movable-bed Froude model...
Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...
Stochastic Analysis and Modeling Levels of a Land-Locked Lake for Resource Development
Lakes are valuable natural resources that can be tapped for recreational, agricultural and other extensive lake side developments. Natural variability of lake levels is an important factor...
