Systems for Reducing Sedimentation in Berthing Facilities
Five systems are described which can be used to reduce sedimentation in harbor berthing areas. These systems, which are alternatives to conventional dredging, are based on either the resuspension...
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...
Implementation of EPA/Corps Site Evaluation Guidance
Past site evaluations have resulted in expensive and time-consuming field studies and a nationwide delay in final designation of interim sites. Recognizing the problem, a joint Corps/EPA...
Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...
Wetland Creation in Baltimore Harbor
Three areas of Baltimore Harbor were examined for use as wetland sites by Interstate Division for Baltimore City. Each site presented unique and interesting challenges to design. Economic...
The London Dumping Convention and Its Role in Regulating Dredged Material: An Update
The United States is signatory to an international treaty that is implemented through the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London...
Tampa Harbor Florida Deepening Project
Tampa Harbor is one of the largest dredging projects ever undertaken by the Corps of Engineers. The major features of the deepening project which presented the greatest problems were the...
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...
Dredge Automation: The State-of-the-Art
Automated control systems are being developed and applied to enhance the productivity and cost-effectiveness of dredges. Referring particularly to hydraulic type dredging plants, the functions...
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...
PCB Contaminated Sediments from Petit-de-Grat, Canada
In Canada, ocean disposal of dredged materials is regulated by the Ocean Dumping Control Act. Included within the schedules of regulated substances are organochlorine compounds, such as...
Dispersal of Wastewater in the Ocean--A Cascade of Processes at Increasing Scales
An engineering system for marine waste disposal is described. Design decisions are based on broad categories of input information: the complete description of the waste to be discharged;...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
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...
Water and Sediment Movement in Irrigation Furrows
Water movement in an irrigation furrow is simulated by numerically solving the governing equations of continuity and momentum for unsteady, spacially varied flow in a pervious bed open...
Stability of Method of Characteristics
For the analysis of waterhammer, the first-order accurate method of characteristics (MOC) has been widely used for which Courant condition for stability has been developed neglecting the...
Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...
Adjustable Speed Pumping for Irrigation Networks
Adjustable speed technology can be an economically viable method of accommodating the significant fluctuations in flow and pressure produced by certain irrigation networks. Combinations...
Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...
Assessing Irrigation Impact on Instream Flow
A hydrologic model to help river system managers determines the demand for irrigation water in a two mile wide strip of land along the river using information which is generally available...
