On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...
Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
Solution to a Waterhammer Problem: A Case Study
Waterhammer is caused by a rapid change in the flow velocity of liquid in a pressurized pipeline. Therefore, the potential for waterhammer exists in almost every pressurized liquid piping...
Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...
An Improved Method to Predict Annual Transit Fare Revenues from Mid-Year Results
Effective short-term financial management of transit systems requires the same three general actions necessary to manage all service oriented industries: 1)monitoring of short term (usually...
A Knowledge-Based Approach to Improve Urban Transportation Decision-Making
This paper describes a microcomputer-based tool that has been developed to facilitate acquisition and improvement of skills in urban transportation decision-making, in an educational environment....
Wind Tunnel Model Studies of Buildings and Structures
This manual provides guidelines on wind tunnel model testing of buildings and structures. Included are procedures required to provide representative information on wind effects experienced...
Microcomputer Applications in Transportation II
This book contains over 80 papers associated with the North American Conference on Microcomputers in Transportation held in Boston, Mass., from June 29-July 1, 1987. The papers address...
Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...
Computing in Civil Engineering
This book contains papers submitted for presentation at the Fourth Annual Conference on Computing in Civil Engineering. General topics include computer graphs, computer aided design, computer...
Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...
Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....
A Stochastic-Conceptual Reservoir Inflow Forecasting Model
The development of a method to improve real-time forecasting of reservoir inflows for the purpose of minimizing water loss through spillage is presented. Streamflow forecasts are computed...
Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...
Development of the Owyhee Dam Hydroelectric Project
The Owyhee Project Power Committee and Owyhee Irrigation District are developing the Owyhee Dam Power Plant, currently under construction in eastern Oregon. The power plant is being constructed...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
Mini Hydro at the Hackett Mills Project
The project includes rehabilitation of a timber crib dam and the first use of a Right Angle Drive turbine in the United States to generate power from the 16 feet of head available at the...
Planning & Execution for Rehabilitation of Large Francis Turbine/Generator Units
This paper highlights some of the constraints in planning and execution of rehabilitation work which must be carried out within an extremely tight schedule, dictated by hydrological considerations...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharges. A simple analytical procedure is presented for estimating the loss in turbine...
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
