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...
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....
Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...
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,...
Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...
Engineering of Controlled-Drainage Systems
Soil-water management by water table control (via a dual purpose subdrainage-subirrigation system) is becoming popular in humid regions of the U.S. and Canada. Controlled-drainage is an...
Tapping Shallow Groundwater with Horizontal Wells
In recent years, horizontal wells have become an economical water supply source alternative for many shallow water table areas in Florida. Horizontal wells typically utilize 15 to 20 cm...
Agricultural Drains and Safety of Dams
Bonny Dam is located in east central Colorado on the South Fork Republican River. The dam's foundation is in the relatively porous Ogallala formation. Throughout the history of the dam,...
