Sediment Transport Rate for Non-uniform Sand
Based on the equations of bedload transport by authors, the functional relation of total sediment transport capacity of flow has been found. The modifying coefficient due to non-uniformity...

Laboratory Analysis of Hyperconcentrations
The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...

Total Sediment Load Calculations for Goodwin Creek
Total sediment transport load of Goodwin Creek was calculated for the period from 10/1/84 to 9/30/88 using transport relations derived from sample data for the fines (< 0.06 mm),...

Estimation of Unsampled Sediment Discharge
A procedure is developed to estimate the total bed material load without using the size distribution of suspended load. Because of the uncertainties involved in the calculation of the...

A Watershed Model of Sediment Transport?Load-I
A watershed sediment transport model has been formulated and optimized upon storm hydrographs and the associated sediment load data for several watersheds that have been urbanized and...

A Stochastic Approach to Sediment Transport in Alluvial Rivers
A dimensionless sediment transport function relation for alluvial rivers has been developed using stochastic approach. The dimensionless function may be applied to estimate suspended load,...

Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO₂)...

Seven Oaks Dam Outlet Works Design
The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps'...

Fixed-Wheel Gates Uses and Limitations
The fixed-wheel type of gate, which derives its name from sets of wheels mounted on axles fixed to the gate, rolls upon and transmits the hydraulic load of the gate to guide tracks bearing...

Determining Hydro Project Dependable Capacity
Traditional techniques for estimating a hydro project's dependable capacity are of limited value when evaluating a hydro project in a thermal-based power system. For such...

Quantifying Uncertainty in Hydropower Planning
Power system operators must deal with various types of uncertainties. Some are related to inputs, such as system load and water supply, while others pertain to the system itself, such...

Efficiency and Vibration Testing
To gather the necessary data to assure the most efficient and reliable operation of the system, Idaho Power Company implemented a plant testing program in 1988. The testing program consists...

Thermally Developed Blade Stresses and Cavitation Damage
Cavitation damage to the turbine runner blades, to the draft tube liner, and to the runner hub requires extensive welding repair. The traditional repair method is to gouge out the damaged...

Design and Installation of Prestressed Rock Anchors for Penstocks at the Sheldon Springs Project
A mini-hydroelectric project producing 25MW of power was recently completed near St. Albans, Vermont. The power conduit conveys water from the intake on the river to a bifurcation and...

Optimization of Power Production Based on Efficiency Data
Computer programs dealing with different parts of the optimization process are in operation in Norway today, and they include: the hydrological part from weather forecast to reservoir...

Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...

Acoustic Flowmeter/Efficiency System Installation at the Niagara Power Project
The New York Power Authority's Robert Moses Niagara Power Project (RMNPP) recently installed an acoustic flowmeter/efficiency system on two 150 MW rated generators. This paper...

Analysis of Unsteady Flows in Irrigation Canals Due to Load Rejection in Hydroelectric Project
An add-on hydroelectric project has been proposed for the Owyhee Tunnel No. 1, a component of the Owyhee Irrigation Project constructed in the 1930's by the U.S. Bureau of...

Foundation Engineering
Current Principles and Practices
The proceedings of the 1989 ASCE Foundation Engineering Congress (entitled Foundation Engineering: Current Principles and Practices) address advances in the state-of-practice and in research...

Predicted and Observed Axial Behavior of Piles
Results of a Pile Prediction Symposium
This publication presents the results of a pile capacity event that was held at the Lakefill site on the Evanston Campus of Northwestern University in conjunction with the 1989 Foundation...
