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...

Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...

The National Dredging Data Management System
The ADDAMS computer program is a collection of user-friendly computer models for planning, designing and managing confined disposal areas. Models which can be used to determine the size...

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...

Linear Programs for Dredging Management Decisions
Recurrent economic concerns facing decision makers in the dredging industry are considered. Problems related to contract bidding, project planning and resource utilization are formulated...

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...

Numerical Model of Mississippi River at Lock and Dam 26
Replacement work was initiated in November 1979. The first stage cofferdam constricted about half of the river channel. As a result, the flow velocity at the constriction increased causing...

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...

Upper Hudson River Valley Dam Break Model
In order to determine areas of inundation due to the failure of Conklingville Dam, a dam break analysis was performed, and the resulting outflow hydrograph was routed through the downstream...

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...

Computer Aided Hydraulic Design of Pipelines
General purpose computer software packages are being used more frequently in the hydraulic design of pipeline systems. The areas where the use of such packages are advantageous over earlier...

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...

Numerical Modeling of Downstream Impacts Resulting from Hydropower Operations
Hydropower peaking operations often have downstream impacts that require an accurate assessment. A one-dimensional implicit finite difference numerical model has been used to accurately...

Evaluation of Two-Stage Outlet Hydraulics
A two-stage detention basin is an effective storm water management tool. This type of basin is designed to control two storm events and it will tend to perform better than a single-stage...

Reservoir System Management for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...

Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...
