Numerical Simulation of Tidal Flow in Shallow Water Bay by Finite Difference Method
A two-dimensional finite difference numerical model to solve the vertically integrated non-linear shallow water equations has been developed using an Alternating Direction Implicit (ADI)...
Impact of Breakwater Removal on Hydrodynamics and Water Quality in Flushing Bay, New York
Hydrodynamic and water quality models were used to simulate the potential effect of removing a breakwater to increase flushing and improve water quality in Flushing Bay, New York City....
Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...
A Modified Adjoint Method for Inverse Eddy Viscosity Estimation for Use in Coastal Circulation Models
The adjoint method is used to develop an objective analysis technique for estimating the vertical eddy viscosity used in three dimensional oceanic models. A cost functional which consists...
A Predictive Model of the Currents in Cleveland Bay
A two-dimensional (depth-averaged) numerical model is proposed to describe the hydrodynamics of Cleveland Bay and is used to investigate the water circulation within the Bay. By utilizing...
Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...
Innovative Reregulation Weirs
Since their construction, hydropower dams have generated more than just power for the Tennessee Valley Authority, they also generated concerns about their effects on river flow and aquatic...
Grouting Against Hazwaste
Grouting has only recently entered the hazardous-waste arena, mainly in the form of positive cutoff slurry walls. At an industrial landfill near Niagara Falls, N.Y., a three sided, single-line...
Better Cover-Ups
Designing the final cover for a solid waste landfill or remediation site is often trickier than designing its lining because a cover will undergo more unpredictable stress and distress...
Earthquake Considerations in Earth Dam Design
In 1963, the writer was engaged by the State of California Department of Water Resources to make a study of the influence of the hazard of earthquakes on the design of embankment type...
Piping in Earth Dams of Dispersive Clay (Paper introduced by Norman L. Ryker)
In 1971 Jim Sherard was engaged to investigate the common failure of a group of Soil Conservation Service (SCS) floodwater retarding earthfill dams built between 1957 and 1970, eleven...
Risk Analysis in Water Resources Engineering: Development and Application
Traditional engineering approaches for evaluating safety and performance in technical projects are usually based on conceptual modeling and the application of engineering standards. Risk...
Risk Assessment or Engineering Standards: Toward a Decision Framework
The Army Corps of Engineers (ACE) publishes manuals, some of which include rules to be followed in the planning of a water resources project. Some of their other manuals simply suggest...
Climatic Change and Ensuing Risks Facing Water Resources Managers
Global climatic changes will have a significant effect on the utilization of regional water resources and will influence markedly the operation and management of water storage and delivery...
Responding to Public Opinion About Cumulative Long-Term Risks: Analysis and Communication of Risks from Climate Change and Hazardous Waste Sites
Public reactions to cumulative, uncertain, and long-term (CULT) risks pose particular problems to risk communicators. Low-magnitude and low-probability risks (e.g., living next to a hazardous...
Overview of AWARE: A Software Tool for Balancing Power and Nonpower Values in Water Resource Planning
Decision Focus Incorporated has developed a software tool for the Electric Power Research Institute to help utilities and other water resource planners examine the social trade-offs between...
The Monitoring of Water Conservation Behavior and Attitudes in Southern California
Seldom are the effects of public information programs monitored and analyzed in a sound, systematic manner. Information on the impact of investments in public information programs is essential:...
An Innovative Institutional Arrangement Which Incorporates the Risk Preferences of Water Users
An innovative institutional arrangement that incorporates the risk preferences of water users is being refined in Australia. It is especially relevant for river and reservoir management...
The Role of Risk Analysis in Feasibility Studies of Water Resources Projects
Many parameters involved in feasibility studies of water resources projects are inherently uncertain. Projections of these parameters based upon extension of past trends can be quite inaccurate....
Nonlinear Diffraction of Random Waves by a Vertical Cylinder
In this study, nonlinear diffraction of random waves by a vertical uniform circular cylinder in deep water is analyzed. The incident wave field is represented by a stationary random process,...
