Hydro Turbine Submergence
The elevation of a hydro-electric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus...

Turbine Improvements through Model Testing, a Case Study
An air-flow, propeller type, rim-drive turbine is being manufactured to be used in sites with heads ranging from 12 to 28 feet. A laboratory turbine model study was conducted to optimize...

Upgrading Open-Wheel Pit Hydro Plants with Modern Submersible Hydroturbines
This paper presents a new approach in rehabilitating open-wheel hydrosites by using modern, standard submersible hydroturbines, open flume type cylinder gates, and high efficiency draft...

65 MW Bulb Turbine Generating Unit for Tadami Project
The Tadami Hydro-electric Power Project (Tadami Project) of the Electric Power Development Co., Ltd. (EPDC) - Japan is now under construction and is scheduled to be in commercial operation...

Model Tests for Six-Jet Vertical Pelton Turbines for Bradley Lake Hydroelectric Project
A model of a six-jet vertical Pelton turbine, including the spiral distributor, 50 feet of penstock, discharge chamber, and short free-surface tailrace was designed, built, and tested...

Analyses of the Lower San Fernando Dam Failure
The main methods employed for the back analysis of the behaviour of the Lower San Fernando Dam during the 1971 earthquake are described. The requirements for a comprehensive analysis are...

Transient Analysis of the Finchaa Hydroelectric Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...

FERC Licensing: The Water Resources Engineers Role
As a result of the Electric Consumers Protection Act (ECPA) of 1986, the Federal Energy Regulatory Commission (FERC) is obligated to give equal consideration to non power uses of hydroelectric...

Modeling Sedimentation Problems at Hydro Developments
Sedimentation embodies the processes of erosion, transportation and deposition of sediments. At hydro developments, sedimentation can create problems. Computer sedimentation models (CSM's)...

Knowledge-Based Expert System for the Real-Time Operation of Reservoir Systems
An efficient way to avoid the loss of valuable knowledge is to develop an expert system which incorporates hydrologic, hydraulic, system analysis, environmental, economical knowledge based...

Visualization of Flow Phenomena in a Hydraulic Turbine Based on 3D Flow Computations
The fluid flow in a Francis turbine has been analysed theoretically. Advanced techniques have been used for both the flow calculation and the presentation of the results in order to clarify...

Experience with the Application of Fully 3D Potential Flow Analysis to Runner Design
Hydraulic turbines come in various shapes and types depending on their operating conditions. Their performance characteristics depend largely on the runner which is the most difficult...

Digital Data Acquisition and Performance Testing of Hydroelectric Equipment
The U.S. Army Corps of Engineers Hydroelectric Design Center has elected to use digital data acquisition methods when conducting performance tests of hydroelectric units. Transducers have...

Coastal Zone '89
Coastal Zone '89 is the sixth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

Multipoint Monitoring
Monitoring groundwater is necessary to guard against pollution and to provide data for water resource management. The Orange County (Calif.) Water District has embarked on a program of...

SPIDA Method for Reinforced Concrete Pipe Design
The required supporting strength of buried pipe is affected by the total load that is imposed upon the pipe and the manner in which the pipe is supported by the surrounding soil. The installation...

Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering in August, 1989 at New Orleans, Louisiana. The objective of the Conference was to provide...

Reliability Analysis of Water Distribution Systems
Prepared by the Task Committee on Risk and Reliability Analysis of Water Distribution Systems of the Committee on Probabilistic Approaches to Hydraulics of the Hydraulics Division of ASCE....

Sediment Transport Modeling
This is the Proceedings of the International Symposium on Sediment Transport Modeling, held in New Orleans, Louisiana, August, 1989. It reviews the state of the art and presents the latest...

Computing in Civil Engineering
Computers in Engineering Practice
This book contains papers presented at the Sixth Conference on Computing in Civil Engineering held on September 11-13, 1989 in Atlanta, GA. This series, initiated in 1978, provides a continuing...
